Send out an SOS with the Pawn Stars when a WWII Morse Code reader clicks into the shop. Will Rick crack the code to capture this rare item or will he send out all the wrong signals? Then, a customer brings in a letter written by Secretary of State John Quincy Adams, who would later become president. Can Rick lead a successful campaign to capture this letter or will he concede the race? And later, when Corey insists on taking over Rick's annual 4th of July barbecue for the shop, will he provide a new spark for an old classic or will his ideas fizzle?
