Olivia Campbell has always dreamed of spending a sunlit night on the frigid Antarctic continent. But as an actuary who assesses risk for a living, she never imagined she would have the chance. So when her career takes an unexpected detour, and her boyfriend—a high-powered art dealer with a taste for the finer things in life—decides to stage an ostentatious, career-making auction on a luxury liner to Antarctica, Olivia is thrilled. That is, until things start to feel a bit strange. In addition to the scores of wealthy patrons and potential buyers, they'll also be traveling alongside a small group of beleaguered employees of Pioneer Adventures—the company responsible for managing the ship—and their charismatic, divisive CEO. When the first bodies are discovered, it's easy enough for Olivia to write it off as a terrible accident. But as the situation heats up and the temperatures continue to plummet, she begins to wonder whether she might have booked a one-way ticket to her own demise.
