Twelve-year-old Hana, heartbroken by her mother’s grave illness, flees home and nearly ends her life—until a floating balloon with a rope ladder lifts her into a vast fortress ruled by Warlocks. Inside, she finds trapped spirits powering the castle’s magic. Disguising herself as one of them, Hana works in the fiery boiler room and befriends an enchanted broom that leads her to freedom.

With a gifted flying bicycle, she enters a magical forest, helps a thirsty old woman—who transforms into a young lady—and rescues a shipwrecked elder. Together, they soar the skies, painting life into clouds. But a Warlock battle interrupts their journey.

A single crystallized tear from Hana, cast into the hearth, breaks the spell. The spirits are freed, the Warlocks age, and peace returns. The dark fortress becomes a place of joy. Flowers bloom, children laugh, and music echoes through its halls.
