Sally Braddock’s serene lifestyle atop a mountain in Vail, Colorado, changes drastically each year when her three spoiled children and their spouses visit her – and her money – for Christmas. They live off their trust funds, which are disappearing quickly, and spend most of the holidays bickering and hitting up their mother for money.
This year, Sally makes an announcement that sends her children into a tizzy, an announcement so extreme that it pushes someone in the house to murder. The storm inside the house is matched by a raging blizzard outside, and the family finds themselves snowbound with a killer.
