Following Kay's disappearance, the Unit goes into damage control, scrutinizing the surveillance footage and following up on the few leads they have - a process that provides an unexpected suspect.

When Church goes undercover to investigate a murder, he inadvertently ingratiates himself with the Rossis, a criminal family currently the target of an independent inquiry. Church is ordered to remain undercover.

With the help of the unit, Church manages to impress Dino Rossi and weaken the position of his right-hand man, who is resentful of Church being accepted into the ranks.

With Church recruited by the Rossis, Angie goes undercover to investigate one of Dino's contacts. Church is falling in love with Dino's sister, Christina, and may ultimately have to choose between her and the Unit.

While the Unit learns of Church's relationship with Christina, Church is forced to come to terms with Christina's involvement with the family business and refuses to testify against Dino.

Information comes to light that someone is trying to sell Dino details about Church. With his identity revealed, it is a deadly race against time for Church to save his relationship and his life.
