Pilar and Isabel. Mario and Jaime. Two mothers. Two children. A new family unit. A new normal. Well, at least that is what Pilar and Isabel hope will happen during their week-long vacation in a rural house: that their respective 13-year-old children will be able to understand their relationship, their love, and that they will be able to connect and accept each other as what they should be: siblings. But, of course, there are many ways to connect and accept each other.

What would happen if, one year, Santa Claus was forced to cancel his Christmas Eve appointment with the world’s children?A few days before Christmas, the famously cheerful and magical giver of gifts has an accident on his sleigh, right in the middle of Madrid. He ends up in hospital, which is where he’ll have to stay until after Christmas. Fortunately, the guy he’s sharing a room with at the hospital, Salva, is willing to step in and take on his all-important Christmas work. But it won’t be easy… the Christmas countdown clock is ticking and Salva has to find the reindeer, learn to fly the sleigh and, the most difficult part of all… learn to be a good person.
