While spending the summer at his aunt's residence, the young yet ill Shou uncovers a remarkable revelation: after trailing the house feline into foliage, he catches a sight of a pint-sized girl roughly the size of his finger! Naming her species "Borrowers," as they subsist on minuscule fragments of human belongings, the girl presents herself as Arrietty. As he learns she resides in the house cellar with her parents, Pod and Homily, Shou becomes wildly thrilled at the notion of such extraordinary neighbors.
However, he overlooks the hardships they endure daily. Besides concealing their existence, they must also venture into human realms, from the home to the outdoors to survive. Despite her parents' cautions, Arrietty befriends Shou, sparking unforeseen incidents that could alter their lives forever.
Captivating the eye and winning the heart, this stunning tale of a bond that bridges the gaps between distinct human species unfolds in a world where imagination and reality intertwine, leaving an indelible mark on both young hearts forever today.
