In 1862, daredevil balloon pilot Amelia Wren (Felicity
Jones) teams up with pioneering meteorologist James Glaisher
(Eddie Redmayne) to advance human knowledge of the weather
and fly higher than anyone in history. While breaking
records and advancing scientific discovery, their voyage to
the very edge of existence helps the unlikely pair find
their place in the world they have left far below them. But
they face physical and emotional challenges in the thin air,
as the ascent becomes a fight for survival.
