After spending nine years apart, 13-year-old Amy (Anna Paquin) and her father Thomas (Jeff Daniels) are finally reunited. But things don't go smoothly at first, and while Thomas spends all his time testing a lightweight aircraft he has built, Amy finds solace with the geese nesting in a nearby lake. When developers then threaten to displace the geese, Amy volunteers to lead them on their migration by flying in Thomas' aircraft.
