Aaron invites his girlfriend Lea and her 8-year-old son Tristan on a trip to the mountains. What could be a starting point of a new life together, slowly turns into difficult territory, as the three fight for their positions within the new family. High up in the Three Peaks region in the Italian Dolomites, Aaron and Tristan are faced with their ambivalent love for and deepest fears of one another, while Lea stands in between the two, trying to navigate this triangle. In his attempt to win the boy's accep- tance, Aaron takes him up the mountain and confronts Tristan with his continuous aggression towards him. When fog sets in and Aaron loses the boy, their power games reach a dangerous level.
