M*A*S*H — Season 4

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.

Frank settles in as commanding officer, only to have a new one appointed over his head, one that, to his chagrin, fits in very well.

A freezing night, an artillery barrage that's coming too close, a patient going downhill, and Frank's searching Hot Lips' tent for his letters.

When Hawkeye's father is notified that he's dead, he finds it's no easy matter either to get word to him or to establish otherwise.

Its quid pro quo at the 4077th: two bottles of Scotch for secret surgery, and a tank to scare off snipers for an unauthorized shot of penicillin.

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.

The 4077th plays host to kids bombed out of their orphanage, and at the same time has to deliver a baby and care for battle casualties.

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.

B.J. writes home to his wife, Peg, reporting Klinger's escape attempts, the visit of a formidable chaplain, and one of Frank's goof-ups.

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 a fever and makes a will, leaving all his money to his wife and all his clothes to Hot Lips.

A wounded colonel's gun, a showpiece, disappears, and Hawkeye and B.J. play a hunch and bluff Frank, who has it, into returning it.

Mail brings a letter to Frank saying his wife is divorcing him, and one to Potter telling him he's going to be a grandfather.

Radar gets the help of Hawkeye and B.J. to procure something Colonel Potter says he's fond of, but that's hard to come by - tomato juice.

Radar writes home to his mother, as Hawkeye conducts the camp foot inspection, and Colonel Potter gets some shrapnel in his backside.

Potter decides Frank would be less of a pain if the others were friendlier to him; they oblige, with some startling results.

Hawkeye is injured in a jeep accident and, aware he has a concussion, babbles to a Korean family to keep himself awake.

Frank tries to distinguish himself by selling the camp garbage, but it's Hawkeye who finds a use for it: he dumps it on a troublesome Colonel Coner.

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?!).

The 4077th turns up a sick helicopter pilot, 'Smilin' Jack, who doesn't want to quit, and a twice-wounded GI who does.

Hawkeye is reunited with a woman he thought was out of his life forever, but who never altogether leaves.

A sudden deluge of wounded at the 4077th is followed by a fire and a rainstorm which makes matters difficult for the staff.

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.
