At Quantico, the recruits are tasked with performing a hostage rescue training exercise that shakes Alex, making her question her ability and whether she should quit Quantico. While in the future, Alex continues to search for clues, finding one that questions the innocence of one of her closest classmates. But is her clue really what she thinks? No one is who they seem.
Simon helps Alex avoid being captured by the FBI. They track the wire from her apartment to one of Shelby's companies and search for evidence at her house. Shelby knows that Simon is officially undercover for Clayton and Ryan discovers it, too. In the end, Alex holds Shelby hostage, Ryan and Simon plot together, and Clayton announces Alex is shoot-to-kill. At Quantico, Alex still struggles with what she learned about her father and fails during a training raid of a hostage situation. Liam wants Ryan to get Alex to quit Quantico and Ryan finds out that his undercover assignment was never officially sanctioned. Miranda asks Nimah to return to Quantico and tells her how her son was influenced by extremist groups to plan an attack on his high school. Elias becomes more suspicious about Simon.
