Noah is only days away from his first trip back to Nice since he was a child when a social worker calls looking for a temporary home for Michael, his eleven-year-old great-nephew. Though he has never met the boy, he gets talked into taking him along to France. This odd couple, suffering from jet lag and culture shock, argue about everything from steak haché to screen time, and the trip is looking like a disaster. But as Michael's sharp eye and ease with tech help Noah unearth troubling details about their family's past, both come to grasp the risks that loved ones take for one another, and find they are more akin than they knew.
