Ryder and Pepper McCoy are the pampered sisters of the Highland McCoys - Heath, Philip, Jaxson and Tennessee. The brothers have always been over-protective of the girls, vetting every man who is brave enough to even ask them on a date. Both sisters are spirited, giving their brothers a run for their money - but one is about to give them a heart attack. Two men are vying for the hand of Ryder McCoy, Samson Duke and his brother Gideon. But this isn't a rivalry, the Duke brothers plan on sharing her. They are determined to lasso, corral, and mark the feisty filly with the DD brand.
