In a heartwarming short film lasting about 15 minutes, exclusively screened at the Ghibli Museum, we follow Koro, a young girl's beloved puppy in a quaint town. When the girl unintentionally leaves the gate open on her way to school, Koro seizes the opportunity to explore the town's streets. Along his journey, Koro encounters various characters like a girl on a bicycle and a kind elderly dog with its caring owners, all while his worried owner and her father canvass the town with 'Lost' posters. After a series of adventures, including a nap under a delivery van, Koro catches a familiar scent and joyfully reunites with his adoring owner near their home.
