Rocker Ozzy Osbourne was one of the pioneers of the celebrity reality show genre when he and his family members were the subjects of a popular series that showcased their home lives. In his return to the genre, Ozzy and son Jack head out on the road for a father-son journey that has been years in the making for the self-proclaimed history nerds. This isn't like the road trips Ozzy took when he was touring with roadies and tour buses. Instead, it's just him and Jack visiting iconic and historically significant locations and landmarks that are on the duo's bucket list. The Osbournes' destinations range from typical tourist traps like Mount Rushmore and the Alamo to niche attractions such as a tank collector's private museum of working war machines.

Ozzy and Jack head to Arizona for a camping trip with Jack's daughter Pearl; Jack's plans to take the family to the Grand Canyon go awry; Ozzy seeks an unconventional method of treating his neck; the men visit legendary rock star Billy Idol.

Ozzy and Jack endure a long drive to Utah's San Rafael Swell to visit the Mars Desert Research Station; along the way, the men visit Jack's survival expert friend and spend the night in a Native American tepee complete with flat-screen TVs.

Ozzy is hounded to do press, promos and photos for his final world tour; needing to stay behind in Los Angeles for his baby's birth, Jack conspires to convince his sister, Kelly, to take the wheel and hit the road with Ozzy.

With Jack stuck in Los Angeles waiting for his baby to be born, sister Kelly hops into the driver's seat; in Arizona, Ozzy and Kelly tour the Biosphere and bond over a night of beauty masks.
