When a college student and his girlfriend are found shot to death in known gang territory, is it a case of gang retaliation, or were they simply in the wrong place at the wrong time? Under pressure from Brenda's rival, Commander Taylor, the Priority Homicide Division is brought in to investigate the murders. At first it looks like an open-and-shut case, but when Brenda and Sgt. Gabriel interview the parents of the young man who was killed, they discover that things might not be as they seem. Suspecting that the parents are covering for their son, Brenda digs deeper and reveals some shocking evidence related to their alibis. Meanwhile, Brenda's mother, Willie Ray, comes to L.A. for an unexpected visit and Fritz finds himself entertaining her while Brenda works. With their impending move-in on hold, Fritz uses his charm - and his FBI training - to keep their secret from Brenda's suspicious mom.
