Detective Sergeant Abe Lieberman is about to wake up to every policeman's nightmare--an out-of-control colleague hell-bent on revenge. After gunning down his wife and her lover, a fellow cop, Bernie Shepard has retreated to a makeshift bunker atop his high-rise apartment buliding, armed with a high-powered rifle and enough explosives to destroy a neighborhood. Holding his former comrades Lieberman and Bill Hanrahan desperately at bay, he issues his single demand: a confrontation with police captain Alan Kearney--or else, widespread slaughter. Either way, Leiberman knows, it's a choice that can only end in disaster.
