Other Title(s)借りぐらしのアリエッティ
SynopsisThe original, Carnegie Medal-winning 1952 novel revolves around the “little people” — 10 centimeters (about 4 inches) tall — who live underneath the floorboards of an English country house. Ghibli’s adaptation will transport the setting from 1950s England to the Tokyo neighborhood of Koganei in 2010.

Shou moves into his great aunt's house. Living there already are a group of tiny people, The Borrowers. A 14-year-old Borrower named Arrietty strives to prove herself by helping her father gather materials that her family needs from Shou's new home. Arrietty soon discovers Shou breaking the rule that humans must not know about The Borrowers' existence. As Shou and Arrietty's relationship develops, human interference endangers The Borrowers' lives. Arrietty and Shou must work together to try and protect The Borrowers' way of life.
