In this gory sci-fi outing, shot and originally released in 3-D, Dr. Paul Dean (Robert Glaudini) is a scientist living in the near future, after America has fallen under the control of a repressive paramilitary regime. Deans research causes him to absorb an especially voracious parasitic worm, which feeds inside the human stomach until it becomes strong enough to burst out in search of a new host. In time, Dean is able to extract the creature from his body, but soon it escapes from captivity, and Dean and his friend Patricia (Demi Moore) must find a way to stop it as they find themselves on the run from brutal government agent Merchant (James Davidson) and a gang of thugs led by Ricus (Luca Bercovici). Parasite was Demi Moores second film, shot while she was still a regular on the daytime serial General Hospital. ~ Mark Deming, All Movie Guide
