Ozzy and Jack are hitting the road, traveling the states from Florida to Alaska and everything in between. And they're doing it, per Ozzy's request, in a vintage 1973 GMC camper--the same RV Ozzy toured in with Black Sabbath when his career in America was just beginning. At their Key West starting point, Ozzy and Jack do some deep sea fishing, pay a visit to Robert the Haunted Doll (where they pick up a souvenir mascot to ride up front in their GMC), hunt for pythons in the Everglades, and drive by Mar-a-Lago, President Trump's Winter White House.
Ozzy and Jack go to a NASCAR race, but the RV breaks down, so a racing expert from Georgia comes to theuir rescue, gives them a place to stay for the night and teaches them about dirt track driving. Later: Ozzy and Jack visit an Elvis museum; drive tanks; and visit a guitar diddley bow artisan before heading to Texas for the NASCAR race.
Jack and Ozzy take a trip down to Cajun country, where Jack's in-laws live in Louisiana. In New Orleans, they take a trip down memory lane with an old family friend from Ozzy's early touring days. Never ones to shy away from the eerie, Jack and Ozzy pay a visit to a French Quarter landmark and one of the most haunted houses in America. And finally, the boys partake in a classic bayou tradition--a good ol' family crawfish boil!
Ozzy and Jack head to Arizona for a family camping trip with one of the littlest Osbournes, Jack's daughter Pearl. It's nothing, but stargazing and campfires for the Prince of Darkness and his granddaughter. Jack's plans to take the family to the Grand Canyon go awry when neither Ozzy nor Pearl want to go. In Sedona, Ozzy seeks an unconventional, new age method of treating his neck. The men say goodbye to Pearl and make their way to Sin City to visit Ozzy's old friend and legendary rock star Billy Idol.
Ozzy and Jack are headed to Mars! Or at least the Mars Desert Research Station in Utah. As the men traverse one of the most beautiful states in America, they must also endure the long drive to San Rafael Swell, where the research station is located. Along the way, the duo visit Jack’s survival expert friend in hopes of learning skills for any sticky situation. They also take time out from the road to spend the night in a native American teepee… complete with flat-screen TVs. When they finally make it to the research station, will Ozzy and Jack survive life on Mars?
Hitting the Pacific Northwest, Jack and Ozzy learn about competitive lumberjacks. Then Jack finds himself bed-ridden with the flu. So Ozzy steps up and visits a coffee roaster himself and gets super caffeinated. After Jack recovers, they visit an oyster farm and then visit a medium who has agreed to tell them if Robert the doll is evil.
Ozzy is planning his final world tour, but is hounded to do press, promos and photos which he hates. He tries to persuade Jack to hit the road but Jack has one problem–his new baby is due to be born and he can’t leave LA. Ozzy and Jack conspire to convince his sister, Kelly to take the wheel if Jack has to stay behind.
Ozzy and Kelly are frantically awoken in the middle of the night by a call from Jack that his new baby is going to be born tonight. They quickly pack up the RV and a very exhausted Ozzy and Kelly make their five hour trek back to LA; they don’t want to take any chances. During their brief time in Los Angeles, the Osbournes manage to welcome a new family member, squeeze in a quick camping trip to Joshua Tree, and even have dental surgery, all while acquiring a new “road dog” for the rest of the trip.
Now that Jack's baby has been born, he's once again traveling with Ozzy and his sister, Kelly. They explore the state of New Mexico, sampling chili milkshakes, chainsaw sculpting and learning to make pistachios. Kelly hates dealing with all the guy humor that Ozzy and Jack deal out, but figures out a way to make a profit from it.
Ozzy, Jack and Kelly arrive in Missouri, and it's already, "Game On," between Jack and Kelly as they've agreed to plan each alternate days' activities. Kelly takes the guys to eat some fresh ice cream, but Jack fires back with a trip to a Mining, aka, an 'Explosion School.' But both Jack and Kelly have also planned some touching surprises for Ozzy as well. Which is good, because Ozzy and Jack's old nemesis 'Robert the Doll' has returned, and threatens to derail the trip with his evil curse!
For the first time in World Detour history, Kelly heads the trip. This time it's to Nashville, Tennessee. Jack and Ozzy are backseat to some very "Kelly" activities including, a drag queen brunch, visiting Manuel, Nashville's iconic fashion designer, and restyling Ozzy's Madame Tussauds' wax figure. Not entirely excluding her father and brother's interest, the Osbourne trio visit a chocolate and record pressing factory. Kelly plans a musical surprise for Ozzy, and squeezes in a quick trip to the largest ashram in the country where they meet a Guru with some helpful meditation tips before Ozzy's tour.
Jack and Kelly have succeeded in getting Ozzy to Florida in plenty of time to have some World Detour fun. Unfortunately, Ozzy's holed himself up in his hotel room, and won't come out until the tour starts. Undeterred, Jack and Kelly decide to bring the fun to Ozzy! They visit a chocolate sculptor, who's made an amazing chocolate bust of Ozzy that they bring back for Ozzy to admire... and eat? They also visit the famed Fountain of Youth, to retrieve some magical water for Ozzy before his tour. Also, Jack arranges for a well known psychic to visit with Ozzy, and get rid of any bad luck before Ozzy takes the stage at a gigantic music festival!
