M, ¿nunca seré nadie?

Alex, an underground movie writer, homosexual and in his thirties, is bored, the worst sin for somebody taken as creative. His world is deleting itself and the background is black. Casually, he reads a note about the debut as director of an ex-friend. Some people seems to get some success, many others gave up. But what about him? What has he done, why he can't even look at himself at the mirror?
