Check out the German film by that title. It's the story of a volitile piano player wrongly imprisoned, sprung from jail to play one stunning piece in a competition. It's all about the last four minutes, but the you really need to see everything that comes before it to fully appreciate it (so skip the excerpts on youtube). It's not a bad film up to that point, but the last four minutes will blow you away.
(For non-German speakers or the subtitle phobic, you don't know what you're missing!)
