In a cozy little cheese factory lives a family of gray mice. Their life is perfect: a warm, snug home, a well-ordered routine, and a well-mannered son. But their peace is shattered in an instant when a new family of white mice moves in.

A true mouse war begins, filled with Shakespearean drama! The mutual animosity between the gray and white parents grows worse as their children fail to understand the reasons for the adults' hostility. The young mice like each other so much and long to be friends, leading them to bravely seek help from the Great Cat.

Through a whimsical and enchanting plot, the theater gently explores serious themes with children—how to stay true to yourself in life, remain authentic even in the name of the highest ideals, and never lose the most precious qualities: the ability to love, to befriend, to believe in miracles, and to truly see and hear those around you.
