Christian (Jean-Paul Rouve), is a visionary scientist who studies migrating geese. His son Thomas, age 14, is obsessed by video games – His thoughts of spending a 3-week summer holiday alone with his father on a Camargue farm are nightmarish. Remarkably enough, father and son bond in a joint effort to save an endangered species of geese thanks to Christian’s pilot skills with ultra-light aircraft. Preparations begin for an extraordinary and perilous journey -- the pair plan to lead the geese they’ve raised onto new and safer migration routes.
Adventurer, explorer, director-coscreenwriter Nicolas Vanier adapts his own eponymous novel, itself inspired by the incredible true story of Christian Moullec (co-scriptwriter).
