It's 1862 and scientist James Glaisher (Eddie Redmayne) and widow Amelia Wren (Felicity Jones) embark on a remarkable mission to go where no human has gone before: 37,000 feet into the sky in a hot air balloon. As they begin their journey into the unknown, we flash back to their reasons for taking this momentous step... Battling weather conditions and their uncertain vessel, can the two return to Earth safely?
Based on a true story, Tom Harper (Wild Rose) reignites the wonder of flight with some truly spectacular visions of air travel. Redmayne and Jones - reunited once again following The Theory of Everything - are charming co-leads, bringing the innocence and joy of exploration to vivid life.
