Almost Royal

Siblings Poppy and Georgie are on a mission to find out what the future holds for the human race, starting with a simulated trip to Mars. Next up they meet people who are hoping to survive the apocalypse before joining a political candidate with a more hopeful vision. Star Trek legend George Takei guides them on their quest.

Poppy and Georgie investigate the American system of law and order, joining the police in a sleepy Louisiana town, learning that not all dogs are cute and cuddly, and that hosting doesn't always mean being polite to your guests. The Carlton's also travel to the very end of the country to meet the Border Angels, who offer help to migrants on their way into the United States. Questions are put to YouTube superstar and ‘crime expert' Jimmy Tatro, which leads to confusion, rather than clarity.

Tonight's episode sees the siblings taking on the alien world of work, starting with a consultation on how to create the perfect résumé, then cooking up a storm in an American diner, before taking to the city streets as drivers for rideshare company Lyft. The episode also includes the Carlton's attending a job fair to show off their new skills and make an inspirational speech. TV star and entrepreneur Lisa Vanderpump is on hand for advice.

In the season finale, Poppy and Georgie Carlton immerse themselves in American holidays, learning about the lovely pre-Christmas event that is Thanksgiving by attending and giving a speech at a parade before making themselves at home with a host family who are kind enough to offer them dinner. They also attend Tu Bishvat, Groundhog Day and steal the show in an elaborate production of the Nativity. TV personality and fashion designer Whitney Port is on hand to help them through the festive maze.
