The Aftermath (1982)

(a.k.a. Zombie Aftermath)

After a lengthy space mission, two astronauts (Steve Barkett and Larry Latham) return to an Earth transformed by nuclear war. As renegade gangs and mutants rule Los Angeles, the astronauts join two pretty women and a couple of kids in a growing resistance movement. This sci-fi adventure follows the men as they battle bell-bottomed biker leader Cutter and his brutal gang.

The Aftermath was on the Section 3 Nasties List  and was liable for seizure and forfeiture by the police. Passed without cuts in 1988 on the Goldcrest video label.
