Sky chasers

A encounter with a boy dangling from the sky changes pickpocket Magpie's
life forever. Like her, the boy dreams of flying over the
rooftops of Paris. His family, the Montgolfiers, are desperate to
be first to discover the secret of flight. Together with Pierre,
Magpie is soon caught up in a world of inflatable bloomers, spies
and a trio of unruly animals in a race to be the first to fly
a hot air balloon - in front of the King and Queen of France.
