On a quiet night, a speeding car crashes the happy life of music professor John (William McBose William Mapother). His wife and daughter and the good life are taken away by the underage girl Rona (Britt Marling Brit Marling). The accident also dealt a great blow to Rona's heart. The sense of guilt made her live the lowest life, but she could not escape the condemnation of her soul. By chance, she met John again and walked into John's hopeless life in the name of a cleaner. After getting along for a period of time, they gradually warmed each other's scarred hearts. At the same time, humans have discovered a planet that is very similar to Earth, and there seems to be another human being living there. Is this a hope or a beautiful dream? This film won the 2011 Sundance Film Festival jury Special Award.
