In yet another ostensible thriller about deadly germs wreaking havoc on human life and psyches, this is a frenetic, uneven story about germs going berserk in a sealed-off lab, giving rise to infected humans more berserk than the germs. The lab is secretly developing weapons of biological warfare, and when an accident occurs that immediately seals off the building, it looks as though some of the workers have died from their exposure to the invisible killers. But, lo and behold, these apparent corpses leap up from death and, rabidly homicidal, they can hardly wait to kill off any human in their vicinity. This makes the potential victims about as vicious as their attackers in their need to escape from room to room, turning the lab into a kind of asylum for the homicidally insane. No wonder that chief cop Cal Morse (Sam Waterston) has a job and a half on his hands — made worse because his girlfriend (Kathleen Quinlan) is in there with the loonies. ~ Eleanor Mannikka, Rovi
