The bizarre results of genetic experiments performed by Dr. Foster (George Gerard) for the head of the sinister Talos Corporation create chaos. When bitten by the spawn of one of the alien spores contained in the lab, Foster undergoes a horrific transformation and begins stalking anyone unfortunate enough to stray into the facility. This includes the daughter of the creature's first victim (Tara Leigh) and a hitman (Tony Gigante) hired by sleazy Talos director Dr. Viallini (Marcus Powell) to murder anyone privy to the project or it's lethal outcome. Ultimately, the survivors must square off against the ever-mutating Foster/thing before it becomes unstoppable.
