Kathleen and Yannick have not spoken for nineteen years, not since what happened with their daughter. Now, there's unexpected news from the other side of the country, and the call for a road trip they can only make together. As they rattle over two thousand miles in a pick-up, through forests, over mountains and into service stations, an alluring history reveals itself - of fierce love, complicated ex-wives and headstrong children, and of a unique bond that never really went away. As they drive, argue, weep and reminisce, an unexpected future for this once estranged couple begins to emerge. Moon road captures the ups and downs of seeing children grow up; of recovering from long buried pain, and rediscovering those closest to us when we think we know all there is to know; of learning to live and love in a completely new way, deeper and more joyous than ever.
