"Beware the Creeper"
Jack Ryder is the anchorman of a show in which he deliberately antagonizes his guests to raise attentions on hot topics, like stem cells therapy and medical nanotech.
While searching a scoop on the revolutionary "nanocells" therapy of Doctor Vincent Yatz, a mixture of nanotech and stem cell therapy able to enhance the body regeneration to the point of giving a new skin to a badly scarred burn victim, Jack is caught up in an attempt by mobsters, to steal Yatz's newly discovered tech.
Unable to escape, Yatz injected into Jack's body the last sample of nanocells - still unstable, in an attempt to keep it safe from the villains.
But when they shoot Ryder in the head, the regenerative substance interacts with his body chemistry resurrecting him as the Creeper. Ryder dispatches his opponents, discovering that now he's able to call forth his bestial alter-ego at will.
