In this low-budget horror opus, Jeff Fahey plays a mortician who has been experimenting with a chemical formula that brings dead bodies back to life. His latest version of the serum is successful, but there's a catch -- his revived corpses only stay alive for an hour at a time. But when a banker threatens to foreclose on his funeral parlor, the mortician is able to mobilize an army of the undead to do his bidding and get revenge. The mortician is soon using his charges to settle scores against a number of people he doesn't like, but when his assistant finds out, he realizes the mortician must be stopped. Corpses also stars Robert Donavan and Tiffany Shepis.
