Wanting to escape the hospital and the glare of family and friends, he decides to hit the road in an old camper van, accompanied by Joanne (Camille Lou), a young woman who has answered his ad. For Joanne, the trip represents an unhoped-for chance to escape a life that has become unbearable. Their impromptu destination: the Pyrenees. Their incredibly beautiful journey overturns their certainties and brings out feelings they thought they'd never experience again... Based on the bestseller by Mélissa Da Costa
