An experienced male nurse in a private clinic has a secret, in certain extreme cases he will euthanize patients. When a new nurse arrives he slowly becomes friends  with the him. However he soon realizes that the new guy is a sociopath and a killer.

This  thriller is a bit too low key for my tastes at first, there was a bit too much talk. That said the film has haunted me since I first saw the film last year at Fantasia. While I had reservations when I saw it almost a year on I jumped at the chance to repost my review because It changed in my mind because the the film has haunted me since I first saw it. 

Give it a shot.
