Synopsis
Having survived being riddled with bullets at the end of Creature from the Black Lagoon (1954), 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 ichthyology student Helen Dobson. Helen and Clete quickly begin to fall in love, much to the chagrin of Joe Hayes, the Gill Man's keeper.

Gill Man takes an instant liking to Helen, which severely hampers Professor Ferguson's efforts to communicate with him. Ultimately, 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 then track down Helen and her amphibious abductor, nearly killing the creature. Gill Man leaves for the ocean and escapes.
