Another day, another nightmare in the BAU as the team is faced with a new, unfamiliar challenge: Taking down a terrorist cell known only as the Sinners. Having been stumped for months, a new agent is brought in from an illusive espionage branch of the BAU. Astoundingly underwhelming on the outside, the team takes her as just another set of hands for the job--until a new lead brings them directly back to her, and her labyrinth past.
