After a horrific motorcycle crash, an injured woman (Marilyn Chambers) receives experimental surgery that saves her life, but side effects leave her thirsty for blood -- and give her a ghastly capability to extract it. Worse, her victims become just as bloodthirsty! Soon, the entire city is thrown into chaos. Bleak, disturbing and gloriously low-budget, this gruesome chiller from writer-director David Cronenberg is not for the squeamish.
