Swamp zombies

A mad doctor at a large metropolitan hospital has invented a serum to raise the dead. When a surprise inspector visits the hospital, he must hastily dispose of his test subjects in the local swampland.

After storm, his creations rise and these flesh-eating zombies wreck havoc on a group of college students. A hermit, karate-chopping ranger, and bikini clad female try to stop these flesh eaters!
