Christian is a visionary scientist who studies migrating geese and working on a lifetime project. For his teenage son Thomas, the idea of spending a summer holiday alone with his father on a farm in the middle of nowhere with no WiFi, is a nightmare. However, father and son begin to bond as they come together on a madcap plan - to save an endangered species of geese. With Christian’s pilot skills and an ultra-light aircraft, they begin preparations for an extraordinary and perilous journey - the pair plan to lead the geese they’ve raised onto new and safer migration routes, guiding them to Norway.
