Zach Sobiech is seventeen when doctors tell him the osteosarcoma in his leg has spread to his lungs and there is no more treatment to try. Director Justin Baldoni follows him through the months that follow, as Zach picks up a guitar instead of retreating from his friends and family, writing a song called "Clouds" as a way of saying goodbye on his own terms. The film sits with him in ordinary rooms, at home, with his girlfriend, with his parents, and lets the camera catch the small talk alongside the terminal diagnosis rather than dramatizing either one. "Clouds" gets recorded and released, with proceeds going to a cancer research fund set up in his name, and the song's reach becomes part of the story the film is telling. Zach Sobiech died on May 20, 2013. What the film leaves behind is not a lesson about dying well but a record of a teenager choosing what to do with the time he had left.
