Award-winning British drama based on the biography by Alexander Masters. The story revolves around reclusive author Alexander (Benedict Cumberbatch) and homeless alcoholic Stuart (Tom Hardy) who become friends when they meet during a campaign to release two charity workers from prison. As Stuart tells Alexander about his traumatic life, Alexander asks Stuart if he can write his story. Stuart agrees but suggests that Alexander write the story in reverse, so that it's more exciting for the reader. As their remarkable friendship develops, Stuart gradually begins to recount his life backwards.
