Synopsis by Fred Beldin
There's an underwater menace haunting the Everglades, killing local fishermen in horrible ways and stealing equipment from a nearby research laboratory. Despite the presence of danger, marine biologist Dr. Richardson (Jack Nagle) welcomes his daughter Karen (Valerie Hawkins) and her sorority sisters to his home on the canal for a relaxing weekend of swimming. Karen meets Dr. John Hoyt (Joe Morrison), the doctor's handsome assistant and sparks fly; she also fends off the affections of Egon (John Vella), the ugly, awkward jellyfish researcher who has always loved her from afar. Egon is treated with derision by the other members of the team, and all of Karen's friends are uneasy around him, so the scarred, sensitive recluse becomes even more withdrawn. When a boatload of dance-crazed biology students arrives for a beer blast, the eerie half-man, half-jellyfish monster makes an appearance and attacks a beautiful girl in a swimming pool. Panic ensues, with deadly results. The scientists struggle to understand just what they're up against, while the murders continue and Karen is eventually targeted by the weird mutant monster. Famed pop star Neil Sedaka provides two numbers for the soundtrack, including the ska-flavored teen dance hit "Do The Jellyfish."
