Who is the sibling of the borrower that is trapped in the freezer?
Young Pete Lender is setting up traps around his house, explaining to his parents that things in their house are being stolen, despite his parents believing they are simply misplaced. However, it turns out that a family of tiny people ("Borrowers"), are living in the house, borrowing stuff without being seen. Pod Clock and his children, Arrietty and Peagreen, make their way through the kitchen to "borrow" the radio's battery.
Arrietty, while treating herself with some ice cream in the freezer, is accidentally shut inside just as the Lenders return. Pod manages to rescue Arietty, but jams the ice cube tube in the process and is forced to leave one of his gadgets behind, which is found by Mr. Lender. Meanwhile, the will of Mrs. Lender's aunt Mrs. Allabaster is the only proof that the house rightfully belongs to the family, yet their lawyer Ocious P. Potter cannot find it and has already made plans to demolish their house in order to build condominiums on the land, and the Lenders have until Saturday to move away.
Arrietty is trapped by Pete, who is actually astonished to discover the Borrowers. Pete also explains to Arrietty that the house is being demolished due to the absence of Mrs. Allabaster's will, meaning that both families will have to move. After Arrietty explains the situation to her family, Pod reluctantly agrees to have the family move to the new house, despite being somewhat upset that Arrietty has defied so much about the way of the Borrowers. Unfortunately, during the journey, Arrietty and Peagreen fall out of the moving truck and make their way back to the old house, where they find the new house on a map.
