In a magical toy store that comes to life by the power of imagination, the eccentric, 243-year-old proprietor has decided it is time to pass on his shop to his young and unsure manager, a former child prodigy with dreams unfulfilled. The shop, a wonderland brimming with whimsy and fantastic toys that seem to possess a life of their own, reflects the lively spirit of its owner. However, the transition is anything but smooth, as the manager doubts her ability to match her predecessor's magical touch, fearing the store's unique charm and the magic within will wither away under her care.

As the news of the impending transfer spreads, the shop begins to lose its magic, leading to disarray among the toys and diminishing the store's enchanting ambiance. Amidst this turmoil, an introverted accountant with a penchant for order and no belief in magic is hired to assess the store's accounts. His pragmatic and disbelieving nature clashes with the magical reality of the shop, setting off a series of events that challenge the staff and patrons to believe in the impossible. Together, they embark on a mission to save the shop's magic, learning valuable lessons about belief, self-confidence, and the power of a vivid imagination along the way.
