Belker tries to renew his expired driver's license; Renko tries to take his father home from the hospital; LaRue rehabilitates himself with Furillo; and everyone follows the trail of the gun used to kill two officers during a burglary.

Washington's guilt over shooting a bystander resurfaces; Hill's vagabond father pays a visit; Belker goes undercover as Santa Claus; and Bates spends the holiday in the hospital.

The only witness to a massacre in a gay bar is an off duty cop; the Cisco Kid ties up traffic; and Goldblume offers to be Fay's natural childbirth coach.

A judge intent on elevating jail conditions releases the court's overflow back into the streets; Bates has a rocky start as roll call sergeant; another professional hit covers up the murder of Whitney Barnes; after his memorial service, Furillo follows Esterhaus' last wishes to scatter his ashes on the Hill.
