The Glitter Dome is a bar frequented by the Hollywood police detective division (the name is a slang reference to Hollywood). When the investigation of a high-profile studio president is going nowhere, the case is handed over to two experienced detectives, Al Mackey (Garner) and Marty Welborn (Lithgow). For this case, however, they need help, which they receive from a pair of vice police called the Ferret and the Weasel and a pair of street cops commonly referred to as the Street Monsters, due to their fondness for violence.
