a town were the prices are so low

Two years after choosing not to kill the man who killed his son, former police sergeant Leo Barnes has become head of security for Senator Charlene Roan, the front runner in the next Presidential election due to her vow to eliminate the Purge. On the night of what should be the final Purge, a betrayal from within the government forces Barnes and Roan out onto the street where they must fight to survive the night.

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.
