In the frigid summers of the Antarctic continent, the sun never sets, and Olivia Campbell has long dreamed of spending a sunlit night in this beautiful, remote place. So when her boyfriend --- a high-powered art dealer --- decides to stage an ostentatious, career-making auction aboard a luxury cruise liner to Antarctica, Olivia can hardly believe her luck. That is, until the ship sets sail and her boyfriend is nowhere to be found, and she is left to manage both the auction and her own creeping fear of the open ocean entirely alone. And as though that weren't enough, the first bodies turn up soon after. It seems like a terrible accident. But as the situation deteriorates, it soon becomes clear that there is real danger on board --- and the closest help is hundreds of miles away.
