There's Something in the Barn

A family of Nordheim fulfills their dream of moving back after inheriting a remote cabin in Gudbrandsdalen, Norway; only Nora, the teenage daughter, is angry about leaving her friends behind. Carol, the stepmother, is trying to put on a happy face for the family, while Bill, the father of Nora and Lucas, is just excited for the adventure and mostly oblivious to the obstacles. In their new home, Lucas stumbles on the strange creatures living in the barn, revealed to be elves. A local man tells Lucas about a local legend where elves must follow three very important "Barn Elf Rules", which Lucas also tries to enlighten his family with. However, they ignore him and proceed to break all three rules, leading to gruesome consequences.
