Texas-based cult director Larry Buchanan made this low-budget horror oddity starring John Agar as Rogers, a geologist who travels through the swamps to see a scientist named Simon (Jeff Alexander). What Rogers doesn't know is that Simon is quite mad and is experimenting on the local voodoo-practicing natives in order to create a mutant being, disposing of the corpses in a pit of alligators. Capturing Rogers' traveling companion, the treacherous Brenda (Shirley McLine), Simon turns her into a hideous monster before his horrible experiments are curtailed. As silly as most of Buchanan's films of the period, this forgettable trifle will be of interest to genre completists only. ~ Robert Firsching, Rovi
