A pair of Germans visiting a remote Greek island go to the beach, and are slaughtered by someone who emerges from the ocean. On the mainland, five travelers are preparing to tour the islands, and are joined by Julie, who asks for a ride to an island that some friends of hers live on. The only one who objects to this detour to the island (which Julie explains has only a few permanent residents, and only sees tourists a few months out of the year) is Carol, whose tarot cards convince her that something bad will happen if they go to the island. The group sails to the island anyway, and while disembarking the pregnant Maggie hurts her ankle, so she stays behind on the boat with its owner. A man attacks the boat, ripping the sailor's head off, and abducting Maggie.
