Preservation of the species and good old-fashioned loneliness get the best of some half-man, half-fish monsters as they leave their undersea home and attack a seaside town, abducting young women to bear their mutant offspring. Cult chiller that picks up where "The Creature from the Black Lagoon" left off stars Doug McClure, Vic Morrow, Ann Turkel. 80 min. Widescreen; Soundtrack: English. Two-disc set.
