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.

This is the story of an isolated Alaskan town that is plunged into darkness for a month each year when the sun sinks below the horizon. As the last rays of light fade, the town is attacked by a bloodthirsty gang of vampires bent on an uninterrupted orgy of destruction. Only the small town's husband-and-wife Sheriff team stand between the survivors and certain destruction.
