In this international spy thriller from writer/director Christopher Nolan, a man (John David Washington) chooses to die rather than give the names of his colleagues. When he comes to in a hospital bed, he discovers it was a test and he has passed it. As he recovers from his near death experience, he's welcomed to "The Afterlife."
He joins a group of international spies, and is given a partner (Robert Pattinson), all of whom are all trying to prevent World War Three. Given the code word "tenet," he's told it'll open the right doors, but some of the wrong ones, too.
