Alex receives information about her father and his past at the FBI, and the recruits learn the art of profiling.

The NATs practise surveillance with Miranda and her troubled son. Shelby tries to keep Caleb at arm's length, while Raina allows Simon closer. Alex gets help when she tries to hack an FBI computer.

A terror cell tries to infiltrate Quantico, forcing Miranda and Liam to pay a deadly price. Meanwhile, in the future, Alex continues to get instructions from the terrorist - only this time, it's Claire Haas' life that hangs in the balance.
