When a puzzle in the kung fu journal introduces the students of Faiza's Kung Fu School to the mystery of a lost healing medicine formula, they must use fractions to figure out how the parts of this puzzle fit together. It's not until they catch a thief red-handed that they realize they only had half the puzzle all along.
