The 4077th Mobile Army Surgical Hospital is stuck in the middle of the Korean war. With little help from the circumstances they find themselves in, they are forced to make their own fun. Fond of practical jokes and revenge, the doctors, nurses, administrators, and soldiers often find ways of making wartime life bearable.
Trapper is shipped home while Hawkeye is on R&R. Hawkeye speeds to Kimpo with Radar to catch Trapper's plane, but they just miss him. While they are there, they pick up BJ Hunnicut and take him back to camp. On the way back, BJ is introduced to the Korean War.
Radar is driving Hawk, B.J., Sherman, and Frank in a bus back from a "medical conference" when they get lost. They stop to see if they can find anything they recognize. When they decide to turn around, they find that the bus does not want to start. Radar goes off in the middle of the night for the latrine, and does not immediately return. Stricken, Hawkeye wants to set out to find him, only to be stopped by Sherman. An injured Korean surrenders to get medical help from Hawk and B.J.. Upon Radar return, the Korean helps repair the bus and get them out of danger.
It's Potter's anniversary. While Potter writes home, Frank and Hot Lips have a wood carving made for him, and Radar rescues a horse and makes him a present of it.
Intelligence officer Colonel Flagg, and psychiatrist Sidney Freedman, grapples over the fate of a wounded officer, Captain Chandler, who claims to be Jesus Christ. Perhaps the most poignant scene is when Radar asks Chandler to bless his teddy bear.
Hawkeye tangles with a tough Army colonel, Colonel Spiker, B.J. helps Zale, who's received a "Dear John" letter, and Frank looks endlessly for Korean saboteurs.
Frank has Hawkeye up on charges of mutiny, for usurping his authority when Potter was away on leave, and Frank was the C.O. The Judge Advocate, Colonel Carmichael, tries the case; BJ, Potter, and Radar are in attendance of the preliminary hearing to offer support for Hawkeye. There are several versions of what happened: according to Frank, he was trying to hold the 4077th together during heavy casualties when everyone else was falling apart; according to The Eye Of The Hawk, BJ and Radar, it was Frank who was out of control with his regimen. Finding no evidence of the alleged mutiny, the judge drops all charges against Hawkeye and puts Frank in his place (but will he stay there?!).
Clete Roberts introduces this segment as his show; he's arrived at Korea to interview the staff of the 4077th Mobile Army Surgical Hospital because of its high 97% efficiency rating. In Roberts' interviews with Hawkeye, BJ, Frank, Radar, Klinger, Mulcahy and Potter, they talk about how they cope with their situation, what they miss about home, how they feel about who they work with, and whether they see any good in coming from war.
