A 1990's update on old B-movie nonsense about an intergalactic drug dealer, visiting earth to deliver his narcotics and pay-off line ("I come in peace"). Dolph Lundgren plays the cop who tries to stop him. That's the story.
It's easy to forgive the poor performances and simple plot but the film would certainly be more likeable if some more effort were put into the special effects or makeup. It just looks cheap and shoddy. Direct to video stuff.
