That same night, across the Baltic Sea, a Danish celebrity is at her home, locked in and cut off from the snow. Then she hears footsteps in her living room. Who is in her house?

Police in Stockholm and Copenhagen are closing in on their suspects. But as winter darkens and more people die, their investigations begin to unravel.
