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? “Clever three-part mystery series that tightens the tension screw with great skill and requires the viewer's full attention for its twists and turns. Originally staged and excellently acted in the demanding lead role.” (“Lexicon of International Film") Philippe Kessler, a talented concert pianist, is about to give an important recital in Strasbourg. But more and more, around him, sounds and images become distorted, as if parasitized by another reality. Why is he the only one to hear his piano going out of tune, his playing transformed into a funereal cacophony? As he withdraws, struggling violently against his fear of madness, those close to him worry.
