Train riders are used to stressful delays on the Zero Local line. But when a new passenger shows gratitude to the driver on their daily commute, tensions begin to ease. Eventually the artistic traveler stops riding the Zero Local line, and discord begins to creep back into the train car. Will the regular passengers find a way to restore the sense of camaraderie they once felt? Inspired by a true story, Ethan and Vita Murrow share with us a tender ode to the power of art and its ability to foster friendship and community in the most unlikely of places.
