A voyage from New Zealand to Fiji aboard a large sailboat seems to be a perfect holiday until a mysterious mist appears on the second day and a distress call is picked up on the radio. Going to the aid of the ship in trouble the yacht comes across a drifting fishing boat, and find one lone survivor. When this man is taken aboard the yacht strange events begin to happen and people start acting as if they were not themselves.
