Skin

It's a fairly common, if ghoulish, procedure: the 'harvesting' of skin from corpses for temporary use on emergancy burn victims until their own grafts are ready. But when a team of moonlighting medical students accidentally take skin from the wrong doner, the results are catastrophic: a New York hosptial ward is destroyed in a psychotic bloodbath, and an elderly professor, admitted for a routine skin graft, is suddenly the city's most wanted fugitive.
