A dispute over an up-and-coming singer's success erupts in a gang war that threatens to bring Vic down, too; a case that could help Aceveda's political future sends Dutch and Claudette searching for a missing day laborer.

As Dutch's theory about a serial killer preying on prostitutes proves true, he convinces Aceveda to launch an all out effort to find him before he strikes again; Julien decides to bring down Vic for stealing drugs.
