The White Room(1989)

The Justified Ancients of Mu Mu, King Boy D and Rockman Rock, try to find and gain access to the mystical White Room. They leave a party at their house and drive in their 1968 US Cop Car through night-time London and the dusty plains of the Sierra Nevada region of Spain. There they face judgement: will they be allowed to enter the White Room? Meanwhile their lawyer David Franks tries to find a loophole to free them from their contract with Eternity.
