Vicious young ex-con Justin Casby arrives in town, keen to move in on Roach's territory and killing one of his dealers to force a meeting with Roach himself. However Stannard's men raid most of Roach's distributors, including Xavier, to Cartwright's fury, forcing Roach to find another supplier and taking on board the manipulative Casby. Whilst the Unit learns who is relaying their information to the other side Ash, regarded as a true loose cannon by Cartwright, feels that he is now for the first time on the right road to unmasking Roach as the boss of the drug operation.
