its one of my favorite films. Do you need help?
Basic Story:
Rock star is burnt out after a show, watches TV movie that reminds him of his childhood. He flashesback to his fathers death. He trips out and watches the firebombing of London from his youth. Then he becomes detached from his family, his wife cheats on him. Then he is in a bathroom before a show and having a hallucination that he is a leader of a hate group similar to the nazis who were attacking the jews, because he felt the jews got his father in to the war. Then the judge tells him to tear down the wall.
That a quick enough summary?
