Irritated that the 4077th is planning a "surprise" birthday party for him, Hawkeye aids a wounded surgeon at the front and habitually disagrees with wisecracking medical advisor Dr. Anthony Borelli. Constant interruptions prevent Klinger from frosting a cake in Hawkeye's honor.
Pierce is upset by the fact that civilian doctors are making a lot of money off the war, and decides to bill the army for all his work. Meanwhile, Winchester is reluctantly showing 3 Korean doctors American medical techniques, putting them down all the while, until he is on the receiving end of their expertise.
En route to R&R, Hawkeye is flagged down by a North Korean soldier who holds him at gun point, forcing him to treat his wounded comrade. Back in camp, the officers change partners in a bridge tournament.
To fight an ongoing infection in the O.R., the staff decides to remove the old wood floor and make a concrete one. The surgeons do the menial labor while Klinger acts as foreman (he knows cement and it's not that hard); while an Italian soldier falls head-over-heels for Margaret.
While local orphans attend a Christmas party in the mess tent, Hawkeye, B.J., and Margaret try to save the life of a critically injured solider so that his family won't think of Christmas as the day that their father died.
As the year 1950 comes to a close, the 4077th staff and surgeons hope 1951 is "a damn sight better" and hopefully they'll be going home. The year 1951 is not uneventful: Klinger makes a bet on a baseball team Charles is sure will lose, Hawkeye and B.J. build a kidney machine, Margaret knits a scarf which soon becomes a bed sheet, and Father Mulcahy plants a garden. By the time New Year's Eve rolls around again, they all hope 1952 will be "a damn sight better" and that they will be returning home.
