Dark Blue (2009) - 1x08 - Venice Kings

The team inserts itself into a turf war between the Crypts and a new gang, the Venice Kings, who will stop at nothing to take over the heroin market. Dean goes under as a member of the Kings, working with an informer to bring down the new and, according to Carter, far more dangerous gang. Meanwhile, Ty’s troublesome sister needs $7,000, which Ty and Melissa don’t have to give.
