The Clock family - Pod, Homily and Arrietty - make a new home for themselves with their relatives Uncle Hendreary, Aunt Lupy and Eggletina.
Pod tells the Hendrearys that he and his family are leaving. Eggletina shows them a way out through the scullery drain, but as they make their way, a roaring wall of water rushes towards them.
The Borrowers make camp in Spiller's kettle.
Ditchly and Ilrick's pranks have got the better of them and Pod reminds them what being a Borrower means.
Miss Menzies and George are delighted to find they both know about the Borrowers.
Imprisoned in an attic the Borrowers must escape. They have five days before the Platters are to put them on public display. Arrietty persuades Pod and Homily to build a balloon.
