EW has an exclusive trailer for the psychological drama Elephant Song, which will be making its world premiere at the Toronto Film Festival on Wednesday, Sept 10.

Based on the 2004 play by Nicolas Billion, the film directed by Charles Biname follows a game of quid pro quo between psychiatrist and patient that devolves into manipulation. Psychiatrist Dr. Toby Green (Bruce Greenwood) is tasked with interrogating the enigmatic and troubled Michael (Xavier Dolan), after the last psychiatrist Michael met with mysteriously disappears from his office.

Despite Green’s attempts to control the situation, the disaffected and disturbed Michael starts a game of cat and mouse between patient and doctor. The film also stars Catherine Keener as Nurse Susan Peterson, the person who seems to know how to handle Michael best.
