Into the Forest (2016)

Sinopsis

Tom (8) and Benjamin (11) travel to Stockholm to spend the summer with their father, whom they have barely seen since he divorced their mother. Tom, in particular, knows next to nothing about this strange, solitary man who seems never to sleep. When he suggests they spend a few days at his cabin in the country, the boys are delighted. But the cabin is totally isolated in the middle of a huge forest, a place both beautiful and troubling.
