The sequel to CREATURE FROM THE BLACK LAGOON

Having survived being riddled with bullets at the end of the first film, the Gill Man is captured and sent to the Ocean Harbor Oceanarium in Florida, where he is studied by animal psychologist Professor Clete Ferguson and student Helen Dobson. Helen and Clete quickly begin to fall in love, much to the chagrin of Joe Hayes, the Gill-man's keeper. The Gill-man takes an instant liking to Helen (as he did to Kay in the first film), which severely hampers Professor Ferguson's efforts to communicate with him. Ultimately, the Gill-man escapes from his tank, killing Joe in the process, and flees to the open ocean. Unable to stop thinking about Helen, he soon begins to stalk her and Ferguson, ultimately abducting her from a seaside restaurant where the two are at a party. Clete tries to give chase, but the Gill-man escapes to the water with his captive. Clete and the local law enforcement must now try to track down Helen and her amphibious abductor.
