As Vic tempts Officer Lauren Riley into bed and Ronnie notes that some of the money train cash is missing, the Decoy Team's undercover investigation into a murder-for-hire ring is at risk of being exposed. Hoping to avert the danger, Vic shakes down Desiree, an informant who is dating gang leader Pretty Boy Parems. When Desiree fingers Kaliel "Li'l Psyche" Wilks as the gangster Trish is working on, they warn Walon that his cover is about to be blown. But when Trish cannot be alerted in time, Walon blames Claudette for failing to act on his warning about a mole inside the department who has been feeding intelligence to the gang. Meanwhile, as Dutch enlists Danny in his hunt for the rapist, Tommy learns he's being forced out of the department.
