Parasite's Best Scenes by The B Movie Cut Up

From the Wikipedia Article:
"It is the far future. After an atomic disaster the world is reduced to poverty. Instead of government, the America of this future is run by an organization called the "Merchants", who exploit the degenerate remains of society. The "Merchants" in order to keep control of the populous forced Dr. Paul Dean (Robert Glaudini) to create a new life form, a parasite that feeds on its host. Realizing the deadly potential of such a being, Dean escaped the merchants with the parasite, infecting himself in the process. Now on the run, he travels from town to town, studying the parasite so that he can find a way to destroy it, all the while keeping one step ahead of a "Merchant" named Wolf (James Davidson) that's hunting him. While resting in a town in the middle of the desert, he is attacked by a gang of hooligans (Cherie Currie, Freddy Moore, Natalie May, Joanelle Romero, Tom Villard) led by Ricus (Luca Bercovici), a former slave of the "Merchants". The gang steals the parasite, not realizing what it is and it infects one of the members. Meanwhile Paul befriends a pretty young lemon grower named Patrica Wells (Demi Moore) who promises to help him destroy the escaped parasite. Ricus, trying to save the life of his friend comes to Paul for help, only to be confronted by Wolf. Patrica, Paul, and Ricus manage to evade Wolf, but by the time they return the parasite has spread to another member. Not only has it spread, it has grown, into a fleshy worm with a mouthful of deadly teeth. After killing the parasite in Paul, the worm attacks Wolf and they blow him up."
