It has been wild and windy in Greendale. Pat calls to collect an Australian stamp from the Reverend Timms, who will be visiting London to meet his sister Elsie from Australia.
When Pat arrives at the Post Office, Elsie phones Mrs Goggins to say she will come straight to Greendale because of her flight being diverted to Manchester, and Pat has to catch up with Reverend with the help of Miss Hubbard's bicycle and Ted's roller skates. Will Pat be able to stop the Reverend from catching the train to London?
