The Phantom from 10,000 Leagues

After a succession of puzzling deaths occur along the coast, Dr. Ted Stevens (Kent Taylor), a scientist, and detective William Grant (Rodney Bell), dispatched by the government, attempt to uncover who or what is responsible. But when the victims and their property betray evidence of radiation exposure, Grant begins to suspect that the Pacific College of Oceanography is involved. His suspicions are virtually confirmed when he discovers an associate of the college pacing the shore with a spear gun in hand. They then discover the trail of radiation spills from an unknown origin at the ocean's bottom, which the investigators fear is a monstrous sea beast that haunts the beach in search of prey.
