A five-month-old bar-tailed godwit stands on an Alaskan mudflat in October. It has never migrated before. Eleven days later it lands in New Zealand, 13,560 kilometres away, having never once touched down, fed, or drunk.
This is a film about the animals that cannot stop — and about how we know what they did.
Before the flight, the godwit rebuilds its own body: the gut, liver and kidneys shrink, the flight muscles and fat load grow. It burns its own organs to make the crossing. Nobody saw it happen. The record exists because of a satellite tag the size of a coin.
We also look at the globe skimmer dragonfly, the blackpoll warbler's Atlantic crossing, frigatebirds that sleep on the wing, the caribou, the gray whale, the leatherback turtle — and the Arctic tern, which answers the question in a completely different way.
And then the harder question: what actually sets the ceiling? Why can't an animal simply keep going?
