 When the ordinary citizen Jack DeVries (Chris Mulkey) heists many banks and kills many people, the whole police department chases him under the command of detective Tom Beck (Michael Nouri). They capture him and seriously wounded, he is sent to the hospital, sharing a room with Jonathan Miller (William Boyett), a man with serious gastritis. The FBI agent Lloyd Gallagher (Kyle MacLachlan) comes to the police station looking for DeVries and is assigned to join Tom. When they arrive in the hospital, DeVries is dead and Jonathan is missing. This is the beginning of the hunting for a mysterious and bloody alien.
