Made in Florida in the mid-1960s by exploitation legend William Grefe, STING OF DEATH follows a group of college students who travel south to Florida on spring break with their friend Karen, whose father, Dr. Richardson, is a marine biologist studying jellyfish. At the party, Karen’s friends insult and ridicule Dr. Richardson’s assistant, Egon, who is in love with Karen. Egon creates a murderous jellyfish mutant which begins a killing spree and eventually brings Karen to his secret laboratory in the swamp.
