Plot:
A USCG pilot and his winchman Haig (Doug McClure) answer an SOS call at sea and arrive at a derelict schooner called the Requoit. Haig lowers himself to the ship, where he finds three dead bodies along with one survivor, Eva (Kim Novak), cowering in the cabin. As the pilot attempts to retrieve Haig and Eva with a rescue basket, the line breaks, plunging the two into the ocean. After they swim back to the boat, the pilot informs Haig that he must return to base because his fuel is borderline. Eva and Haig spend the night on the boat, during which time she recounts the story of the storm that killed everyone else aboard. One man was hurled through a hatch; one is hanging from the ship's mast; another vanished before her eyes; and a fourth man is in an aft compartment, floating in the air. Eva attributes the deaths to supernatural causes, but Haig has a practical explanation for everything...
