Here's the official synopsis and trailer:

ENEMY tells the story of a university lecturer named Adam (Gyllenhaal) who is nearing the end of a relationship with his girlfriend Mary (Laurent). One night, while watching a film, Adam spots a minor actor who looks just like him. Consumed by the desire to meet his double, Adam tracks down Anthony, an actor living with his pregnant wife Helen (Gadon) and engages him in a complex and dangerous struggle. The film is a haunting and provocative psychosexual thriller about duality and identity, where in the end only one man will survive.
