Harry Trent (Matt Mitler) is a thief on the run, and decides to steal a space shuttle to escape some security guards. Once in space, he finds the shuttle is damaged and can't return to Earth for five years, which is handy as an alien fleet has just arrived to conquer Earth!
Finally back home, Harry finds the world is now like the one in Mad Max, only with grass and trees. After a fight with inept barbarians in ragged clothes, he meets up with Dana (Denise Coward) and discovers that a secret tape he has (indeed, the reason he was on the run in the first place was because he stole it) contains the secret which will allow scientists to develop a weapon to defeat the aliens. To get the tape to the Professor (Bill MacGlaughlin), Harry and Dana must cross the bad lands (which look quite nice really), battle a warlord called Mad Dog (Joe Gentissi) and fight lots of pig faced aliens...
This is a very strange film that rips off a number of different science fiction films but has plenty of ambition despite the laughably poor sfx. It also has plenty of cheese and weirdness, such as showing how Harry - trapped in space - resorts to drawing a woman's face on a pillow and then humping it! I don't know how they managed it but this film is great!
