Go treasure hunting with the Cajun Pawn Stars as the guys hope they've discovered a 1700's pristine flintlock gun brought to Louisiana by pirates. Can they prove this rifled booty is worth a King's ransom or is it just fools gold? Then, Jimmie travels through country music history as he checks out an old Greyhound bus that may have belonged to country music legend Barbara Mandrell. Will Jimmie pay the right fare for this super-sized ride or will he leave it in the dust? And later, regular customer Joker steers into the shop to sell his motorized wheelchair. Can Johnnie and Fred fire off on all cylinders with an idea to create the coolest ride in town or will Joker be rolling out empty handed?
