Philippe is a rising pianist. An obsessive and compulsive man, he works hard to prepare for a series of concerts at the Strasburg opera. His organized and neat world falls apart on the day of his 40th birthday. Violent fits of tinnitus and strange visions progressively impair his concentration. As a matter of fact, he is the only who hears false notes on his piano…Philippe is no longer in control and slowly tumbles into another world. A world governed by his fears and his anguish, but most of all by a traumatic event that he has buried down deep for over 30 years, back when he was a little boy still…Is he really tipping over into another reality, or is he merely the victim of his paranoid delusions?
