Ozzy and Jack's bucket lists collide when father and son head to the UK. While both want to visit Stonehenge, the mythic structure of Druid lore, the rest of their itinerary is up for debate, and both Ozzy and Jack each want their way. Will Ozzy get his hands on Alan Turing's famous Nazi code breaking machine? Will Jack convince his dad to go to the newly found remains of a Neolithic monument known as "Superhenge"? And will Ozzy let Jack pursue his dream of getting his dad knighted?

Ozzy agrees to go to one of Jack's favorite cities, as long as they'll be able to get a tour of the White House. So, while Jack scrambles to get access to 1600 Pennsylvania Avenue, he and his dad take a bunch of detours. On the itinerary: the FBI Training Facility in Quantico, little known park featuring the heads of America's Presidents, a local legend who calls himself Little Ozzy, and the residence where Ozzy's idols The Beatles partied after their first concert in America.
