A married couple sail the Pacific Ocean to forget a tragic accident. After a month at sea, they sight a mysterious yacht and are boarded by its lone surviving crew member. When the husband discovers the yacht's terrible secret, the crewman goes wild, kidnapping his wife and taking his ship. Terror on the high seas is center stage as the husband fights to keep the mystery yacht afloat and his wife battles the psychotic who's assumed control of their ship.—Tim Kretschmann
