As Wills foils the tramp-catcher aiming to clear Windsor of the homeless in time for the royal wedding Harry and Meghan take Charles to meet her mother Doria in Los Angeles. Unfortunately Harry's stag night antics land him in jail, almost halting the union. Back in London Camilla and Pippa separately plot to sabotage the ceremony whilst Beatrice and her new date Jeremy Corbyn plan to boycott it. With cash-strapped Fergie standing to make a million by commentating for American television it is down to Wills to make sure the wedding goes ahead - though things can still go wrong.
