In September, with the arrival of autumn, there seems to be the loneliness of drama director Caden (Philip Seamer Hoffman Philip Seymour Hoffman). Due to an accidental injury, Caden falls into endless consultation and visits to various professional doctors. On the other hand, Adele (Katherine Keener Catherine Keener), the wife of the miniature oil painting, is increasingly estranged from him, and the cold and awkward family atmosphere deepens Caden's self-doubt, even if his play is a great success. Caden had an affair with a woman who worked in the theater and an actress. After his wife abandoned him, Caden tried to find the possibility of improving his mental state from the two women, but he failed. Caden finally decided to find the answer in the play, and he came up with a complicated creative plan.
