There is not much I can say about this film without spoiling it, so here goes. 

Ethan (Mark Duplass) and Sophie (Elisabeth Moss) seek marriage counselling from a therapist (Ted Danson) who recommends a romantic weekend away to help fix the holes in their relationship.

Debut feature film from director Charlie McDowell (Danson’s stepson) and screenwriter Justin Lader, it was more devised than written. Almost all of the dialogue was improvised around the storyline and for the more complicated scenes Lader would write a few pages as a guide the night before.

The end result is surreal, revealing and eerie.
