After an undercover FBI agent’s body is dumped on the side of the road, all eyes turn toward Dean Bendis (Logan Marshall-Green), an undercover LAPD officer currently embedded with the gang believed to be responsible for the FBI agent’s murder. Dean’s boss, Carter Shaw (Dylan McDermott), is determined to bring the gang leader down while also ensuring that Dean has not turned and switched loyalties. Carter sends in Ty Curtis (Omari Hardwick), who must leave his life as a newlywed to return to the seedy underbelly of the criminal world and get Dean out. Meanwhile, Carter recruits and trains the latest member of his team, Jaimie Allen (Nicki Aycox), a patrol cop who has successfully fabricated her entire past.

Ty goes undercover to search for a gun trafficker, but nearly blows his cover by breaking a crucial rule and seeing his wife on her birthday. Carter must come up with $100,000 to keep Ty's mission protected...and to save his life.

The team goes deep behind the scenes to stop a crime ring which has a big diamond heist planned, with Dean and Jammie pretending to be a married couple to get closer to a major player. Meanwhile, Ty reconsiders his dangerous job after Melissa informs him she wants to start a family.

The team goes after a home invasion crew with Alex and Carter acting as the bait.

The team keeps trying to infiltrate the drug-smuggling ring in order to get to a terrorist. Meanwhile, Alex is offered a promotion in Miami and Ty keeps struggling with his divorce.
