Welcome to the fast life of NASCAR champion Austin Dillon; his wife, Whitney; their adorable son, Ace; and their two best friends, Paul and Mariel, who have a baby of their own on the way. They are all gearing up for the start of race season and the Daytona 500, as the gang heads to Florida to race in the Daytona Duels.

Austin and Paul struggle to get the #3 team back on track after a disappointing race in Daytona where the guys also neglected to properly celebrate their wives on Valentine’s Day. Now they need to make it up to Whitney and Mariel, and also make the right adjustments to challenge for a win at Fontana.

After a second-place finish at Fontana, Austin works overtime with the RCR team to keep up the momentum. While Austin is logging in long hours on the simulator, Paul volunteers to watch Ace for a day and gets a crash course in fatherhood.

Austin has always had luck on his side in Las Vegas, where he has won races in both the truck and Xfinity series. As he looks for his first Cup series win on this track, the girls hit the blackjack tables in search of a little luck of their own.

After the race in Vegas, Austin looks forward to some quality family time as they road trip to Phoenix. Whitney and Mariel are determined to spice things up with some quirky side trips along the way. Left on his own back in North Carolina, Paul tackles the nursery with a design plan that Mariel has definitely not approved.

With Baby Bella due any time, Mariel, Whitney and Austin decide to celebrate Paul’s upcoming fatherhood with a week of tuna-themed fun before the Phoenix race. After all of the “Dadchelor” festivities, Austin looks to score another big finish in the desert.

After a disappointing finish at the Phoenix race, Austin and his team prepare to redeem themselves at the upcoming race at the Atlanta Motor Speedway. When Paul decides to play a prank on Mariel, things quickly spiral into an all-out prank war that gets everyone involved.

After racing on a road course in Texas, Austin is working overtime to prepare for the longest race of the season – a 600-mile endurance test in their hometown of Charlotte. Whitney is busy throwing Mariel the fairytale baby shower of her dreams. With Bella due at any time, the #3 team needs to be prepared if Paul needs to be in the delivery room instead of on pit road.

Mariel’s water breaks and it’s a mad dash to get her to the hospital to welcome baby Bella into the world. New father Paul is able to rejoin Austin and the RCR team in time for their big hometown race in Charlotte. Back at home, the Swans have a surprise for the Dillons.
