Fourteen years ago, the head of a covert biological weapons laboratory was murdered by a notorious psychopath known as Mr. Hell (Larry Cashion) -- who himself was killed while trying to dispatch the scientist's young daughter Tyler. Fast-forward to the present, when the now adult Tyler (Amy Morris) works at the same lab where her father was slain. Unfortunately, a toxic spill brings Mr. Hell back from the dead ... and there will be hell to pay!
