When the cofounder of the trendy London tech startup Snoop organizes a weeklong trip for the corporate team in the French Alps, it looks like any ordinary work retreat. But in this homage to Agatha Christie by the author of The Woman in Cabin 10, a power struggle erupts among the shareholders, and quiet, secretive Liz is at the center of it. Then an avalanche cuts off the lodge from the outside world, and one of their group never returns from the slopes. As the hours pass without any sign of rescue, the chalet grows colder, panic mounts, and the group dwindles further. Each of these ambitious people has something to gain, and now each has something to hide.
