Fiona is the manager of a fast-food restaurant. She lives comfortably and happily with her family in the suburbs. That is until the day she accidentally gets locked into a walk-in freezer. She escapes the next morning, half frozen and barely alive, only to realize that her husband and two children didn't even notice she was missing. But when Fiona develops an obsession for everything cold and icy--snow, polar bears, refrigerators, icebergs--she drops everything, climbs into a frozen goods delivery truck and leaves home. She heads for a real iceberg.
