Trama
John, Lucy and Henry arrive at a remote Christmas-themed hotel for what should have been a much-needed escape, when a sudden blackout turns the festivities into a locked-room murder mystery. Trapped by a blizzard and cut off from the outside world, the guests must spend the night with a killer in their midst. With John reluctantly pulled into one of his strangest puzzles yet, the race is on for the Taylors to solve the crime.
