One day, when the sky grows dark and full of smoke, Soe-In volunteers to travel into the tall mountains to investigate. She's surprised to find a spirit tiger there and learn he has swallowed the sun by mistake!

To help the spirit tiger and her village, Soe-In must come up with a clever idea to solve this gigantic problem. And while she's at it, she just may prove that the smallest people often have the biggest, bravest hearts.
