Ozzy and Jack venture to historic Jamestown, Virginia. Jack is determined to find out whether any Osbournes were among the first British colonists in America, but Ozzy is obsessed with the idea of that the early settlers resorted to cannibalism.

In 1982, something happened at the Alamo that instantly became both Rock & Rock lore and a bold question mark in the Osbourne family history. So, nearly 35 years later, Jack and his dad head back to the "scene of the crime" (against Ozzy's wishes and warnings) in an attempt to uncover the truth and hopefully rewrite history. Along the way the guys take a couple of detours, including NASA's Johnson Space Center, where they test drive the new Mars Rover, and a stop at the Museum of Funeral History.

Ozzy and Jack pack up a camper and travel to the home of all things UFO -- Roswell, New Mexico. While Jack is a true UFO believer and loves camping, Ozzy is a skeptic and loathes the outdoors when it's freezing cold. But Jack's certain that the experience will further deepen their father-son bond.

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?
