An alien travels to earth on a mission to harvest human endorphins to sell on the intergalactic narcotics market. Meanwhile, undercover cop Jack Caine is determined to avenge the death of his partner at the hands of a gang of upscale drug dealers known as The White Boys. Once the cop and the alien cross paths, there’s hell to pay, cars to wreck and shopping malls to demolish.
Yep, I have seen this movie several times.
