An American couple bring their 10 year old daughter, Claire, to her grandfather Lawrence's hotel in The Dolomites, Italy. They usually come for Christmas but this year it’s August. The fact is they are breaking up, and once Claire realizes there’s not going to be a family Christmas this year, she insists on everyone making it out for Christmas in August. Claire, in collusion with her grandfather, plan activities that are designed to re-unite her parents.
Unfortunately the movie A Sudden Case of Christmas is not yet available on HBO Max.
