The Letter (2013)

A remote village in the Northwest of Russia. A mental asylum is located in an old wooden house. The place and its inhabitants seem to be untouched by civilization. In this pristine setting, no articulate human voice is heard, and pain is muted. The landscapes and buildings are not so much inhabited as lightly entwined and then passed through by their anonymous residents, like some creeping mist. Phantoms half stuck, half undone in a phantom world—lost persons from a lost society?

Unfortunately the movie The Letter is not yet available on HBO Max.
