A man wakes up at forty to a broken marriage, a beckoning bedsit, and the realisation that he has done nothing to make himself memorable. Then he clambers into the attic… After a lay-off of 25 years, he seeks redemption via the sixteen feet of treacherous brass tubing he never mastered in his youth. Resuming his old French horn, he sets himself an impossible task: to perform a Mozart concerto in front of a paying audience of horn fanatics.
