Just awful. One of the all-time worst sci-fi pictures. Carradine stars as a mad scientist who makes zombies in his cellar. The "why" is never explained, but the zombies go around ripping out people's vital organs. Enter FBI agent Corey (who died soon after filming) who stands around making
official pronouncements regarding the investigation of this hideous activity. Throw in some Chinese communists and foreign agents from Mexico led by soft-core porn director Russ Meyer favorite Satana, and you've got one really bad movie. Wayne Rogers of TV's "M*A*S*H" fame coproduced and cowrote
this rancid celluloid mess.
