Geraldine and her two daughters, Livvie and Angeline, are living rough on the streets on London. When their van blows up, they must find an alternative place to stay. At first, they live in temporary housing, but the conditions are unbearable. Geraldine reacts quickly and the family decides to take up residence in Scottley's, the best department store in London. They must keep it a secret from doorman Brian (whom the girls call Mr. Whiskers), and a couple of bumbling thieves who want to rob the store safe of its jewels.
