post apocalyptic movie, circa late 80’s to possible 2000, not sure of release. Movie involves a displaced group of young people looking for shelter, this couple takes them in and introduces them to sex drugs and alcohol. The couple comprises a bushy blonde haired mesomorph; his partner is a raven haired asian girl. Both transform into monsters in the end as they were in the beginning. (this was not revealed) The movie is science fiction-horror genre. Thanks
