Jack Whitehall is stuck in the United States with only four days to return to the UK for Christmas. As the clock counts down, Jack sets off on an extraordinary and, perhaps, unbelievable adventure that includes planes, trains, huskies, and bobsleighs. Throughout his journey, a few of his celebrity friends join in, offering their support (or even a hoof!) as Jack maneuvers through the holiday madness in a bid to reach home before Christmas.
