Ashton has 3 kids with Katie, and another on the way. When the family go on holiday with their closest friends and family to New York City for Christmas, they are all having a great time, when Noa, The couples oldest daughter starts getting poorly. When they go to get it checked out, they find a tumour in her brain. Will Katie and Ashton be able to get through this together, or will the pain of losing one of your own, tear them apart??
