Houston cop Jack Caine will not let police procedure prevent him pursuing his mission to wipe out the White Boys, a gang of white collar drug dealers who killed his partner. Caine is partnered with a by-the-book agent Arwood 'Larry' Smith. They investigate the drug theft and the later murder of several key White Boys soldiers by a hyper fast spinning disk. At the same time Caine is made aware - via his girlfriend, coroner Diane Pallone - of a series of drug-related deaths. The corpses are full of heroin, but the cause of death is a puncture wound to the forehead. Unknown to Caine and the cops the deaths are caused by an alien who is extracting something from the victims.
