Will the Borrowers reach the home of their long lost relatives?

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.
