I Come in Peace (film)

Everything About Fiction You Never Wanted to Know.
...But you'll leave in pieces.

I Come in Peace (1990) (released and known worldwide as Dark Angel) is a science fiction action thriller film about a rule-breaking vice cop who becomes involved in the investigation of a number of mysterious drug-related murders on the streets of Houston, Texas. The film was directed by Craig R. Baxley, and stars Dolph Lundgren, Brian Benben, Betsy Brantley and David Aykroyd.

Jack Caine (Lundgren) is a Houston cop who is determined to wipe out the White Boys, a gang of white-collar drug dealers who killed his partner while Caine was waylaid stopping a convenience store robbery. Little does he know that there is a new drug dealer in town, one who preys on heroin addicts in order to get his own drug of trade -- made from the endorphins extracted from heroin users. But this guy's home turf isn't in Houston. It isn't even on planet Earth...
