Dr. John Becker, who operates a small medical practice in the Bronx, is annoyed with his patients, co-workers, and practically everything else in the world. But don't let the curmudgeonly demeanor fool you. As his blind newsstand friend, Jake, and beautiful diner owner, Reggie, would tell you, the rants of the outrageous physician mask a softer side, which he only occasionally displays to his nurse, Margaret, and wacky office worker, Linda.

Jigsaw is back and this time he has locked some very unlucky people in a booby trapped shelter. They must find a way out before they inhale too much of a lethal nerve gas and die. But this brilliant, but disturbed mastermind has left plenty of the traps in the shelter that lead to death also. Now the unlucky are in for a round of horrifying life-or-death games.

Obsessed with teaching his victims the value of life, a deranged, sadistic serial killer is abducting morally wayward people and forcing them to play horrifric games for their own survival. Faced with impossible choices, each victim must struggle to win back his or her life, or else die trying.

A vile, malignant life-form crashes to earth in a cozy, rural American town and eats everything that moves.
