Huldra: Lady of the Forest (2016)

Nanna lives a lonely, regimented life in Berlin. When her life crashes she receives a phone call from her long-lost love Martin, who reminds her of their carefree childhood. Martin wants her to join him for a hike in the wilderness with some of their mutual childhood friends. One of them, Peter (The Swede), has been told of a strange hermetic hippie-like society out in the Swedish wilderness, and the group sets off on an adventure unaware that once they reach their destination nothing will ever be the same again. As they are drawn deeper and deeper into the forest, mysterious events start to unsettle the dynamics of the group. Reality shifts in unimaginable ways, and relations among the friends become strained, then volatile. They had come looking for adventure, but nothing could have prepared them for what lies in wait.
