Nothing much ever happened in the little seaside town of Piedras Blancas...or did, until the mutilated corpses started washing up onshore. Can the investigating scientist (Les Tremayne) prove his bizarre theory that the slayings are the work of some kind of humanoid, amphibious missing link--or more to the point, will he live to? Always-demanded drive-in shock staple co-stars John Harmon, Jeanne Carmen, Forrest Lewis, Don Sullivan. 71 min. Widescreen; Soundtrack: English Dolby Digital mono; Subtitles: English.
