Sulky teenager Thomas (Louis Vazquez) dreads spending summer with his father (Jean-Paul Rouve), an environmentalist in a rural, wifi-less hamlet. Much to his surprise, he grows attached to his father’s new project: an ambitious plan to train a flock of endangered geese to follow a new migratory path, avoidant of pollution and human-made threats. The duo embarks on a journey to the Arctic circle with an ultralight glider, which they’ll fly to guide the geese along their new route. Writer-director Nicolas Vanier (Loup) channels his passion for nature into this tale of our civic responsibility to protect it, a freewheeling adventure of both suspense and enlightening civic action.
