Re-animator

Herbert West is a brilliant medical student who has perfecteda green-glowing serum for regenerating life into dead things – or even parts of dead things. But a corrupt superior, Dr. Carl Hill, assumes control of West’s experiments and winds up, by ghastly necessity, using the stuff on his own severed head and body. West and in-over-his-head co-worker Dan Cain struggle to control the now out-of-control effects of the serum, but the bone-saws and zombies complicate their plans.
