She is staying with friends of a friend, Julie (Rosemarie DeWitt), her husband Peter (John Krasinski), Julie's teenage daughter Kolt (India Ennenga), and their young son. From the day that Martine walks into the the lives of this open-minded, relaxed California family, everything issubtly set off balance....Peter is helping Martine complete the sound design on her art film and they collaborate closely together, working in the studio off the pool house where Martine is staying. They develop a connection that is rare for Peter and necessary for Martine to finish her movie, but which begins to veer away from professional terrain. Each character in Nobody Walks experiences a surge of desire catalyzed by Martine's arrival, and everyone is forced to confront the new landscape that emerges in her wake.
