Mitzi is wondering what lies over the horizon, and she tries her best to see, but to no avail. When George the postman arrives to deliver the mail, he shows Mitzi a postcard of a sandy beach, and Mitzi is excited - it looks much more exciting than the outback, which she sees every day, and which seems a bit flat. Mitzi decides that she'd like to go on a holiday, to see some new sights.
