Premonition writer/director Norio Tsuruta directs iconic Japanese author Kôji Suzuki's tale of open-water terror for the small screen as Showtime's Masters of Horror series winds to a waterlogged close. Jack (Daniel Gillies) is an American lawyer working in Tokyo who is terrified of the sea. But a few small waves become the least of Jack's worries when he and the wife of his powerful client Eiji enter into a dangerous affair. Later, when Eiji personally invites Jack to join the couple for an afternoon boating excursion into Tokyo Bay, the shaken lawyer reluctantly accepts. Little do Jack and Eiji's wife realize that their greatest fears are about to become reality when a presumed pleasure cruise turns deadly personal.
