Diego, a young man with addiction problems, considers ending his life, but his great fear of dying prevents him from doing so—until he sees a television advertisement for "Happy Suicide," a service that organizes suicides for couples. When he arrives at the location, Diego meets his partner, Saúl, a good-natured clown; both are eager to end their lives. What they don't expect is to find that they have only been given one bullet, so they begin to debate who deserves to die more.
