King - Season 1 Episode 2 T-Bone

Homicide is trying to convict two major drug traffickers, the Barrata Brothers, of murder. But when the Drug Squad nails a wise guy named DeMarco for possession, they unwittingly take Homicide's only lead off the streets. Graci hands the mess to Jess, ordering her to solve the murders and bring peace to the cop shop. At the Don Jail, Jess identifies DeMarco's unlikely confidante, a biker named T-Bone, and promises him a break on his own assault sentence if he agrees to act as an undercover agent for the police. Jess puts her trust in her volatile informant, but when T-Bone goes AWOL, he jeopardizes the case and Jess’ reputation.
