Jingle all the way...to murder. When FBI Special Agent Winter Black enters a luxurious Montana cabin two days before Christmas, she's excited because all the people she loves will be joining her soon. Her joy is dashed when an unexpected blizzard hits the area, leaving her stranded and without any means of communication. And she's not alone. Instead of her friends and family arriving, a momma cat shows up at the cabin's door, begging for help. Braving the snow, Winter finds more than just the feline's litter. She finds a dead body. With nowhere to run and thrust into a game of psychological warfare by a killer she can't see, Winter's hope for a bright and shiny Christmas turns into a fight for her life.
