- 11: Two weeks after the 2018 Hostage Crisis ended, Madam President, Claire Haas mentioned that there were eight collaborators, within the shadow, rogue group, that secretly had involvement with the AIC. As a result of Lydia's actions, The Collaborators gained access to sensitive U.S intelligence. This information was vital to their goal of controlling certain areas within the government. As a response, Madam President Claire Haas and CIA director Matthew Keyes assembled a covert task force to remove the remaining threats that the AIC still posed to the public at the time. The primary mission of the task force was to uncover the conspiracy behind the nefarious agenda of the collaborators and expose their involvement in orchestrating the hostage crisis. The task force includes; Alex Parrish, Ryan Booth, Nimah Amin, Shelby Wyatt and Dayana Mampasi. The leader of the group is Clay Haas, a renowned political advisory strategist.
- Prior to the formation of the task-force, Alex is re-instated to work again as an FBI agent.
- The mission of the designated task force is to identify the collaborators of the shadow group behind the G-20 hostage crisis. Some of the collaborators have already accessed the cache that was uploaded by Lydia Hall. Madam President Claire Haas mentioned that the collaborators all fall under one of the key eight “pillars”. The President mentioned that the members want to yield a terrorist act to gain control and influence within the following areas; money, law, logistics, government, technology, ideology, defense and media.
- Matthew Keyes granted Owen an immunity in exchange for helping the task force in accomplishing their mission.
- The task force was assigned a mission to identify whether a collaborator was involved in a cargo plane crash that occurred in Kentucky. Whilst, the team uncovered that a company by the name of GIP profited due to short-selling the cargo that was on the plane, the team later exposed a separate conspiracy. The task force uncovered information about certain GIP high ranking corporate officials being complicit in a Ponzi scheme. Later, it was revealed that Harry Doyle provided specific intelligence on another company named ENGIN. ENGIN was revealed to be an aviator start-up that profited from the crash due to the cargo plane carrying a special aviation technology that could identify where a plane would crash. As a result, the conspirators had the most motive to crashing the plane. Some later, it was highlighted that the involved collaborator in this incident was none other than Christian Kelly.
- Ryan Booth was formally introduced to American-Russian journalist Sasha Barinov at a party hosted by the high ranking corporate members of the GIP. Later, it was revealed that she was able to quickly identify a connection to his real identity through a speedy online investigation.
- León was murdered by unknown assailants. His murder was staged as a suicide.
- In one of the missions of the task force, a collaborator accessed the cache in order to uncover information about emergency-response protocols. Following a news report of a chemical plant explosion in Virginia, the task force team uncovered the information discrepancy surrounding the event in the public media. The team learns that a group of Internet trolls were hired to create the fake news about the explosion from the aid of a private military company called Greypool. The higher officials within the company wanted the city to be evacuated in order to hunt a person of interest. The person in question is Mallory Haynes. She was hired by a U.S Senator to create fake news in order to help with his election. Later, the team exposes the information that the collaborator in connection to the event was none other than Henry Roarke, the Speaker of the House.
- Harry joined the task force on Clay's orders after succeeding in a mission with the team.
- Dayana left the task force and went back to her work life as a cover. She was assigned to be a lawyer on a case in a federal court.
- The task force was assigned a mission to uncover Rebecca Sherman as one of the eight collaborators that benefited from the aftermath of the G-20 hostage crisis. Rebecca Sherman accessed information pertaining to vulnerabilities in U.S passport control, in order to find the means to escape. Whilst, the team uncovered her plan, she requests help due to numerous death threats sent to her by unknown conspirators. As she tries to aid the group in their operation by tracking down a collaborator, she is instantly killed by an unknown sniper. In addition, the collaborator that she tracked down was also swiftly assassinated by the sniper. His name was later revealed to be Thomas Roth.
- Harry left the task force after he had a private discussion with Sebastian Chen.
- Lydia is incarcerated in a federal prison as a result of her actions in the G-20 hostage crisis. She received a visit from her father, Owen Hall.
- A shopping mall was the target of a terrorist attack. Two unknown hitmen connected to The Collaborators framed Raina Amin as the main suspect of the bombing at the Gallow Green shopping center in Beavercreek, Ohio. Prior to being framed, she was kidnapped by the hitmen but then, made an escape to Williamsburg, Virginia. Whilst, Alex realizes that Raina needs help, the terrorist attack is heavily publicized in the media. Due to imminent concerns of a Muslim registration bill being passed in light of the incident, the task force members head to Washington, D.C. to convince the voters to vote no. A senior legislative assistant by the name of Felix Cordova tried to help Clay and his task force by giving them names of the swing voters his boss is targeting for the Muslim registry bill. Clay and his team were unsuccessful in their mission as none of the representatives they targeted were willing to flip their votes because Felix gave them the wrong names. Whilst Clay tries to confront Felix about the issue, Felix mentions that he was just doing his job and that it wasn’t personal. The bill is passed, but Madam President Claire Haas vetoes it. The team realizes that the collaborators wanted Claire Haas to veto it so as to help Henry Roarke in his bid for the presidency.
- Alex and Owen try and get information from a hitman that implicated Raina in the terrorist attack. However, before they could get any information, the hitman is instantly killed by unknown assassins hired by The Collaborators.
- As a result of the attack, an arrest warrant is issued for Raina Amin. Nimah tries to atone for her mistakes at the G-20 hostage crisis and switches places with Raina, so that Raina can continue her work within the task force.
- Ryan found information that exposed journalist Sasha Barinov as an asset for the Federal Security Service of the Russian Federation (FSB).
- Clay Haas visited his mother at the White House in Washington, D.C. He planned on disbanding the task force due to the failure that his team encountered in their previous mission.
- After vacating in Tulum, Mexico, Caleb Haas makes his reappearance in Washington, D.C. He gets in a brief physical fight with his brother Clay Haas after a short conversation with his mother, Claire Haas. Later, Caleb agrees to a living arrangement with his brother at Camp Peary.
- The task force was assigned a mission to uncover a new conspiracy. Although the cache was accessed by the collaborators, their true aim is exposed. The collaborators are seeking to stage a riot in one of five potential U.S. cities. Their purpose is to ignite civil unrest within the United States. The team uncovers that the collaborators have picked Cleveland as a target for their nefarious agenda.
- Cleveland was chosen as there was a rising civil tension due to an almost-hung jury in a case that dealt with gun laws that Madam President Claire Haas passed earlier via an executive order. Although, the collaborators have exerted their influence to convince the judge to push the case through. Sometime later, a guilty verdict was announced for the defendant. After the verdict was publicized in the media, Madam Claire Haas takes a preemptive stance. The President makes a statement to address an angry crowd in front of the courthouse. When she admits that she made a mistake by signing the executive order, she will try to work on fixing the issue with the current legislation framework. As a result of her actions, she gains positive appraisal from the public.
- Sometime after the events of the 2018 Hostage Crisis, Miranda left her position as a Deputy Director of the FBI and became a Special Agent in Charge of the FBI outpost in Cleveland.
- After a short physical fight with Owen Hall, Sebastian Chen clarifies his investigative role into exposing the names of the collaborators. By providing the necessary intelligence to the task force, their mission is considered a success. They expose the following names of the eight collaborators; Thomas Roth, Christian Kelly, Henry Roarke, Rebecca Sherman, Alice Winter, Peter Theo, Maxwell Fletcher and Warren Shepherd.
- Sasha Barinov calls Peter Theo under the pretence of fact-checking a journal story, but he quickly realizes that she’s digging where she’s not authorized, and he hangs up after making a subtle threat.
- Sasha Barinov is killed in a car bombing.
- As Clay realizes that the collaborators are aware of his plan to take them down, he makes a decision to initiate a mission during his engagement party. The covert team were tasked to bring the collaborators in one room to turn at least one of them against Roarke and the others. While most of the team members fail to do so, Ryan is able to get Alice Winter to confess to the murders of León Velez and Sasha Barinov, and seemingly gets her to cooperate, telling him she'll bring two others. Sometime later, it was revealed that Alice instigated an incident to publicly expose Ryan Booth. She ordered for a news reporter to uncover Ryan's connection with an illegal domestic intelligence operation that was unsanctioned by the United States government.
- After the engagement party ended, Owen suggested to Alex that in order to catch the collaborators, she would need to join their side. In order to successfully side with the group, she would need to send them the team's files. After The collaborators gathered intel about the task force, they leak the information to the public, putting the presidency of Claire Haas at risk.
- Caleb Haas left Camp Peary in order to continue his studies at UC Berkeley.
- After news of the unsanctioned nature of the covert team were publicised in the broadcast media, Henry Roarke took the opportunity to criticize Claire's presidency and called for her impeachment. Clay and the team (minus Alex and Owen) try to dig up dirt on Roarke that would prevent him from becoming President, while Raina tries to get help from Felix in finding Nimah. Clay and Shelby try to put emails in Felix's phone to make it look like Roarke is collaborating with Russia regarding cyber-terrorism, but fail. As a result, Felix quits his job and breaks ties with Clay.
- Alex tries to work with the collaborators to gain intel about their group. She worked with one of the members, Alice Winter by getting Matthew Keyes to resign from his position as the Director of the CIA. Later, they go to the FBI Headquarters in Washington, D.C. Alex realizes that Alice put a water bottle in her purse, which contained a gas to poison the agents looking into the scandal involving Madam President Claire Haas, making her look guilty as a result.
- After Claire Haas resigned from her presidency as a result of a national scandal, it was revealed that Roarke succeeded in being appointed as the President of the United States. A week after his inauguration, Mr. President Roarke signed 30 executive orders in five days and removed the cache from the internet, leading Owen to realize that the collaborators are near their end-game. With Clay gone, Alex gets help from Will, Miranda, and Keyes to help find what Roarke is planning. Will learns that the profit made from ENGIN Industries was from the Avionics systems, which have since been added to a number of air-planes. The team finds that there is hidden code in the software that allows a plane to be remotely controlled with a smartphone if they have a popular app installed, created by a collaborator. They realize Roarke's plan: six flights each have one person on Roarke's Muslim Registry Act, each with the app on their phone; when their phones connect to the plane's Wi-Fi, the collaborators will use the app to control and crash the planes. Alex goes to Alice to find the flights, while Shelby, with Raina's sacrifice, finds Clay to learn the FAA's code to request emergency landing. The team successfully save the flights. However, Roarke uses the team's win as an example: he requested them to perform an off-book operation, and uses it to request a new Constitutional Convention, to rewrite the US Constitution.
- After Mr. President Henry Roarke exposed the members of the task force to the public, he had a short discussion with Alex at the White House. From the conversation, it was implied that Alice Winter was killed as a result of a failure in killing Alex and containing the situation.
- In the days leading to the Constitutional Convention, the covert team starts vetting for Mr. President Roarke's new government agency, while secretly trying to stop Roarke from getting the votes needed to allow the Convention to occur. However, their plan are initially foiled by one of the members of the collaborators. Later, the team, with help from Will and Iris Chang, decide to use an indirect approach. Will and Iris pick up Peter Theo from a bar, and locate incriminating evidence of Roarke, which they give to the FSB, in exchange for them requesting Roarke to add a modification to the new Constitution. At the convention in Philadelphia, Roarke's conversation with the FSB is recorded. Alex publicly broadcasts Roarke's recordings and emails the evidence to the ACLU and other rights organizations, before having Miranda fake her death. Mr. President Roarke, not willing to face the press or the police, commits suicide.
- Miranda is incarcerated in a federal prison due to orchestrating Alex's murder at the Constitutional Convention.
- Due to Alex committing treason by releasing classified U.S intelligence to the public at the Constitutional Convention, she is branded as a fugitive of the United States. Owen mentions to Alex in the car that she needs to maintain her cover so as to evade capture from domestic and international law enforcement agencies as a result of being issued an INTERPOL Red Notice for her arrest. Along with Ryan, she left the country on a plane to an unknown international destination.
- Two months after the demise of former President Henry Roarke, it was highlighted that the covert team were celebrating in the bunker.
- It was revealed that Clay and Maxine eloped sometime after the Constitutional Convention event.
- Owen Hall was pardoned for his false arrest in relation to the Jeremy Miller murder case. Later, he was given an opportunity to serve in the role of the Deputy Director of the CIA.
- Shelby Wyatt is given an opportunity to serve as an instructor at the FBI Academy in Quantico.
- Raina Amin and Nimah Amin are freed from prison and pardoned for their earlier case arrests.
