Family relationships have always been perplexing and troublesome. Aaron is a man who, after being in a relationship with the charming Lea for few years, invites her and her 8-year son Tristan on a trip to the magnificent Italian Dolomites. As it often happens in life and in families, what should have been a nice adventure turns into a painful drama. As people often say, difficulties unite families and make their members be more kind to each other. However, when Aaron, Lea and Tristan find themselves up in the mountain, their efforts to feel like a regular mother, father and son, are tested beyond limits.
