The booking of a drunk clown and a mishap involving airplane lavatory ""residue"" pale in comparison to what becomes the day's priority for the sheriffs—finding a ruthless murderer. Barnes hopes an ex-con now in the business of gang intervention can lead them to the killer, and, during a frightening confrontation, Rico's respect for his training officer increases.

A shootout erupts between warring gangs at a funeral, but the situation becomes more complicated when Rico and Barnes realize that the sister of a gang member in the Eastside Brims is in love with the brother of the leader of the Westside Blackstones. Meanwhile Barnes must keep his temper in check after finding out that his 15-year-old daughter, Maya, has a boyfriend. And the deputies must find dates for the upcoming L.A. Peace Officer's Charity Ball.
