Despondent that the funding for his cherished limb regeneration research is to be - pardon the pun - cut off, biologist Curt Conners turns himself into a guinea pig - and finds himself transformed into the lethal Lizard! The rapacious reptile seeks refuge in the dank recesses of the New York City sewer system - pursued by our fledgling web-spinner! But unknown to them both, something far more mysterious lurks in the subterranean shadows - something known as the macabre Man-Thing!
