Bo and Luke are suspected of running a smuggling ring when they deliver cars to Augie Detwiler - the owner of the derby in town, but when they are told about the smuggling, they decide to investigate by joining the derby.

Bo and Luke are given counterfeit money from Granny Annie, the local artist. They investigate to find out where it came from but it turns out to be her. Boss Hogg finds out and wants the engraving plates that make the bills, so he can sell them to big-time counterfeiter Big Jim Downey. But when the Dukes try to retrieve the engraving plates by taking them behind Downey's back, their trickery could have deadly consequences -- and let's just say it would not be a good death -- for Boss. The Oak Ridge Boys perform "Old Time Lovin'" at the Boar's Nest.
