Since Lewis has unsuccessfully been partnered with every member of the squad, the newbie (Kellerman) is assigned to him. Their first case involves the shooting death of an elderly lady waiting at a bus stop. A young man has captured the shooter stashing his gun, but he has trouble getting the cops to watch the tape. Howard has made sergeant and is trying to establish her authority in the squad, but irritates her colleagues. The climax is an arrest of the groom during a wedding ceremony.
