The Pawn Stars travel to Utah for a rare shot at a 19th century Hotchkiss Revolving Cannon. A rapid-fire weapon used decisively in the Spanish American War, will Rick overwhelm the seller with an explosive offer, or will negotiations hit a turn for the worse and blow up in his face? Then, Corey and Chumlee try to get the party started, when an antique Wurlitzer jukebox grooves its way into the shop. Will the guys be able to stay in tune long enough to make a deal or will they be left singing the blues? And later, a woman comes in hoping to sell her antique medical quackery device. An electric zapping machine called a "Master Violet Ray," will this piece of weird science heal all of the shop's problems or cause them to seek a second opinion?

The Pawn Stars are off to the races when a guy brings in a 2000 Porsche Carrera engine that has been recovered from a junkyard. Can this deal go through firing on all cylinders, or will the engine's questionable history make the negotiation run out of gas? Then, the guys pace themselves for a showdown when a seller brings in an early 19th century dueling pistol. Just half of the original two-gun set, will they drop some Hamiltons on this rare piece, or will they misfire and have to run for cover? And later, Rick is ready to rock when a hat once owned by Lynyrd Skynyrd front man Ronnie Van Zant comes into the shop. Will he give a sweet home to this piece of music history, or will the seller fly free and keep the hat for himself?
