Racing Wives will follow the lives of five women living in the "opulent, eye-popping mansions" of Lake Norman, N.C. Three of the principal cast — sisters-in-law Ashley and Samantha Busch and Whitney Ward Dillon — are married to NASCAR drivers (Kurt and Kyle Busch and Austin Dillon). Also in the cast are Mariel Lane, Ward Dillon's best friend, and Amber Balcaen, an aspiring racer who has left her home in Canada in a bid to make her name in the sport.
