Paige Vickers needs a new life, so she's relieved when she's given an assignment that takes her away from her stressful position as a psychiatric nurse with the CIA and puts her in a job as administrative assistant for Vanessa Johnson, an instructor for undercover operatives at the CIA's training facility. At the same time, Damian Schmitt has been transferred to become a part of the Saint Squad—an elite group of Navy SEALs. However, on his first training mission with the team, he is almost killed, and the team suspects that the nearly fatal exercise was no accident. Then tensions accelerate when the rest of the squad is deployed on a secret mission—only to come up missing. When the Saint Squad's disappearance endangers Paige's boss, it is up to Paige and Damian to discover what has happened by going undercover to Maracaibo, Venezuela, the city of Damian's childhood. The shocking twists and turns keep all the members of the team guessing as they push to find out who is responsible for the attacks on the tightly knit Saint Squad.
