Unlike the original novel, the film is structured, according to novelist David Mitchell, "as a sort of pointillist mosaic: We stay in each of the six worlds just long enough for the hook to be sunk in, and from then on the film darts from world to world at the speed of a plate-spinner, revisiting each narrative for long enough to propel it forward." The film consists of six interrelated and interwoven stories that take the viewer from the South Pacific in the nineteenth century to a distant, post-apocalyptic future. Action, mystery and romance weave dramatically through the story as one soul is shaped from a killer into a hero and a single act of kindness ripples across centuries to inspire a revolution in the distant future." "Cloud Atlas explores how the actions and consequences of individual lives impact one another throughout the past, the present and the future.
