Steven is a failure in life: his acting career did not work out, his wife left him, his daughter condemns him. Josh, on the other hand, is lucky. He is handsome, world famous, amazingly talented, happily married. In the play about Byron, Josh shines in the title role. And Stephen is his stage double. But since Josh is depressingly healthy, even after nightly revelry he never disrupted the performance and always, to the delight of the audience, went on stage. Stephen suspects that he is not destined to appear on stage in Byron's costume. He feels that his life is over. At Josh's party, Steven meets a beautiful, witty woman. But even here he has no luck: Nora, the woman to whom he gave his heart, is Josh’s wife. Stephen faces a difficult choice: accept Josh's tempting offer or confess his love to Nora and give up his career in show business. Is he ready to be an eternal understudy?..For the first time in Russian!
