Klinger surprises Col. Potter by being in full dress uniform. He insists he 'grew up' and wants to be in the Army. While in his office. the Colonel receives a call from Headquarters saying that all military money, aka scrip, would be exchanged the next day, red replacing the current blue. No traffic would be allowed in or out of camp while the exchange takes place beginning at 1600 hours. In post-op, Hawkeye examines Corp. Boone, one of his patients. An MP named Maxwell visits him. When Potter makes the announcement of the exchange, Boone asks Maxwell to exchange 400 dollars for him. Charles has a suit made for him buy local tailor Kim. When he asks for payment, Charles asks to help him exchange the scrip the locals have before the deadline for 10 cents on the dollar. Kim is savvy that Charles gets 90 percent profit, but Charles offers him 2 percent of that. When Kim asks why, Charles tells him it's about the opportunity. Kim keeps reducing the price, but Charles says either take a check or get the cash tomorrow, so Kim agrees. After he leaves the Swamp, Kim tells Hawk and Beej about the scheme. They decide to get back at him for it, so they arrange for Hawk to exchange Boone's scrip for him while Maxwell goes to bust Charles and his scheme. Later, people pay off debts, such as Margaret paying a poker debt to Father Mulcahy. Potter comes in and announces that Klinger has been approved to take the test to enter the U.S. Military Academy. Klinger tells him that his Uncle Gus(who tried to get out of World War I as Gussie) is friends with a local congressman, which Margaret laments. Klinger says that Army has a good chance to beat Navy in football. Igor insists Zale pay off a debt. He does, but Igor insists it was double or nothing. Zale says no, and they argue, which ends with Igor shoving Zale's food plate in his face. Zale chases after Igor and they fight in the compound. Hawk and BJ break them apart and Potter confines them to their tents for 48 hours. igor says he's going on R and R but when Potter asks if he wants to go for double or nothing, Igor leaves. As everyone leaves, Hawkeye realizes he left the bag with Boone's scrip on the table, but when he goes back, the bag is missing. The next day, he asks Charles for a loan but he refuses. When Hawk goes to tell Boone the truth, he offers to pay back the money, but Boone thinks it's a scam and calls him a phony. Mulcahy delivers a scathing(for him) rant on the PA asking for the money to be returned. Charles exchanges the villagers' scrip for a 10 dollar bill despite them only having 95 dollars. Klinger starts the exam, but is stumped by many of the questions, as Potter and BJ expected. Charles is stopped on the way back to camp by a roadblocked manned by Kennedy, saying the road is mined. He tells Charles he can only walk, as it is over a hill, but it will take an hour. He stops a local woman for directions, then gives her a coin. The three hour time limit ends for Klinger with him getting one question right: his name, and Potter has to correct him on that. Charles arrives at the camp just after the traffic curfew begins with MP's blocking the entrance. This includes Klinger, who is now wearing a sailor's hat, saying he hopes to get to Annapolis soon and that Navy has a good chance of beating Army. Hawkeye and BJ arrive and Charles asks them to exchange his money for him. They give him the same deal he gave the villagers, 10 cents on the dollar. He gives Charles 40 for Boone's 400. When Charles says it's highway robbery, Hawk turns to Klinger, aka Shore Patrol, and says that Charles wants to report a crime. Later, Hawk gives Boone his new 400 in the new scrip. Boone apologizes, then the Padre comes in saying someone left 400 with him in new scrip. Hawk shows the money he just gave Boone and tells him to use the other for the oprhanage. Mulcahy says that there were two atonements with one speech. He wonders aloud if he could do something over the PA every week. Hawkeye says, 'I wonder if thou shouldst,' and Mulcahy says, 'It was just a thought.'
