After boarding the ocean liner SS Constitution, Lucy goes ashore just one more time to kiss Little Ricky goodbye, and misses the boat. As a result, she ends up hiring a helicopter to drop her off on the ship. 

Lucy and Ethel go looking for Queen Elizabeth II on their first day in London. Ethel manages to get a glimpse of the Queen, but Lucy misses seeing her. Eventually, Lucy finds out that she can be presented to the Queen if she is one of the performers in Ricky's show at the London Palladium.
