Harmonize with some Cajun flair when a seller brings in a rare 1915 Gibson duel harp guitar. Will Jimmie hit a string of good luck by making a deal or will a bad chord leave things unsound? Then, Johnnie and Fred look to get their hands dirty by checking out a crawfish business. Will the guys dig deep to fish out their wallets or will negotiations become too slippery to hold? And later, Jimmie has the opportunity to buy a disposable handgun dropped behind enemy lines during WWII. Known as `The Liberator,’ can Jimmie pull the trigger on this sale or is the seller just blowing smoke?
