Concert conductor Olivier Bressel retires exhausted to his dressing room after a charity concert, refusing to meet officials or attend a reception. But when he goes into the shower, he finds there a young woman with a gun. She tells him to dismiss his dresser and manager, but when they return later it is the girl who is found dead and Bressel's fingerprints are on the gun. Olivier Bressel is found in a room with his fingerprints all over a gun and the body of a dead woman at his feet. Did he either really commit a murder or he was framed?
