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

With supplies low, the 4077th gets a truckload of ice cream churns and salt tablets. But what it needs are light bulbs, and in the dimly lit post-op Charles makes an error for which he draws the ultimate wrath of his two surgeon bunkmates. Meanwhile, B.J. receives a mystery novel that everyone in camp reads in turn. The last page is missing and the solution to the mystery is undiscovered until B.J. calls the author by long distance.

After a delay of three weeks, five sacks of mail arrive, and everyone in camp reacts to good and bad news from home. Hawkeye receives love letters addressed to another Benjamin Pierce, another man has approached B.J.'s wife, and Radar's mom has found a boyfriend. Klinger: "I may not have a family in Toledo, but I got one here."

Charles takes amphetamines to keep up his energy level, and even drugs Radar's mouse, "Daisy", so that it will win a race against a Marine's mouse, "Sluggo".

The doctors have to deal with a short supply of morphine and too many patients while klinger has to deal with a corporal who may be crazier than him -- he shoots down imaginary enemies.

A strong windstorm affects the M*A*S*H personnel in varying ways: Hawkeye and most of the unit busy themselves securing items that could blow away; Radar prepares his animal hutch for the worst; a disgusted Charles switches his Tokyo-leave transportation from air to ground, and runs into a difficult medical situation en route to Seoul.

In this unique episode, the camera becomes the eyes of a young wounded soldier. It records his sensory responses to being wounded, flown by helicopter to the 4077th, examined, operated on, and treated in post-operation.

Hawkeye and B.J. discover that Charles is living the life of Riley, thanks to the attentions of his menially paid Korean servant, Comrade Park, a man of unusual skills. He has an important contribution to make - a native remedy for a seemingly insoluble medical problem.

Radar, who is smitten with the cute new nurse, Linda Nugent, relies on Hawkeye's expertise on how to cope with the situation. Hot Lips, meanwhile, celebrates her just-granted divorce by taking a step that arouses Colonel Potter's ire.

A clumsy foot soldier, 'Look out below' Conway, finds the quickest way to the crew's heart, boosting morale at the 4077th by cooking gourmet delights. Only Colonel Potter, burdened with a personal crisis, is immune from the high spirits enveloping the hospital.

A Congressional aide, Williamson, visits the 4077th on a supposedly routine fact-finding tour, but it's discovered that his motives are far deeper - too uncover Margaret as a communist sympathizer. His case is full of innuendo, so the gang set out to help Margaret.

On leave in Tokyo, Radar is desperately needed back at the crisis-stricken 4077th, but his return is delayed by outside events. While casualties continue to pour in from the front, the 4077th's generator conks out, and the backup has been stolen, depriving the medical unit of all electrical power. But Klinger, filling in for the vacationing Radar, lacks the expertise and experience to wheel and deal for a new machine.

As company clerk Radar O'Reilly reluctantly prepares to depart the 4077th, the unit is still without electricity due to a broken generator, and the operating room continues to fill up with war wounded as night falls. The responsibility for procuring a new generator falls on Klinger, who lacks Radar's masterful knack of cutting through red tape in search of much-needed supplies.

Hawkeye is appointed temporary commander of the 4077th when Colonel Potter rushes off to Tokyo on a mysterious mission. While in command, Hawkeye's main problem is housing a large group of Korean refugees comprised mainly of rambunctious children who need medical care.

Tired of their constant complaints about the quality of recreational activities at the 4077th, Colonel Potter appoints Hawkeye and B.J. as the new morale officers. Winchester's morale has already reached a new peak: He's ecstatic about his operation on a wounded soldier, Sheridan, which saved the boy's leg, leaving only "negligible" side effects - less use of his right hand. However, the soldier was a concert pianist before the war, so Winchester obtains music written by Maurice Ravel for a pianist that had lost a hand in World War I.

Klinger redecorates his quarters, but the resultant ridicule he receives drives him to new heights in his efforts to get out of the Army. Meanwhile, the doctors are perplexed by the reaction of an Asian-American war hero who tries to kill himself when he's told that he will be going home. Sidney Freedman is called in to assist.

A no-nonsense Colonel, who is notorious as a hard-nosed disciplinarian, visits the 4077th during an outbreak of April Fools' Day pranksterism. Colonel Potter tries in vain to halt the mayhem before Colonel Tucker arrives in camp.

On his way to some R&R in Tokyo, a North Korean soldier forces Hawkeye to perform an emergency roadside operation on his buddy.

Members of the 4077th share their impressions of war in response to letters from fourth graders in Hawkeye's hometown. Margaret writes about how there are some patients she will never forget, whilst the Colonel tells of his days as 'Hoops' Potter. Hawkeye: "Dear Ronnie, it's a shame to let the love you have for your brother turn to hate for others. Hate makes war, and war is what killed Keith. I understand how you feel. Sometimes I hate myself for being here. But sometimes in the midst of all this insanity, the smallest thing can make my being here seems worthwhile. Maybe the best answer I have for you is that you look for good wherever you can find it."

A jilted Italian soldier, Corpsman Ignazio De Simone, is smitten by Margaret; Klinger pours a cement floor in the operating room to fight the spread of germs.

Klinger is so depressed by news that his ex-wife plans to remarry, he reenlists for an additional six-year hitch. Meanwhile, a male nurse has a gripe against the army.

Hawkeye uses a bottle of vintage wine to lure unsuspecting nurses into his den; and Potter tries to secure a different sort of anesthetic when the army threatens to ban a painkiller.

The 4077th is given a gift of fresh-grown vegetables by a grateful Korean; and Potter questions the veracity of an upbeat letter from Radar.

A touring USO show brings an unexpected touch of vaudeville to the 4077th when the star showgirl requires an emergency operation. And wouldn't you know, the comedian is Klinger's hero!

Hawkeye is outraged when a sensationalistic war correspondent, Clayton Kibbee, reports irresponsible G.I. stunts as tales of military valor. Kibbee: "As for the last two pints of blood, there's no big finale, no heroes. They helped an old soldier, who'd had visions of glory but finally got it through his thick head how tragic and inhumane war can be. Maybe he'll know better next time."

Charles has a serious toothache, but hates the thought of having anything done about it. The doctors suspect prejudice when an inordinate number of black casualties are brought in from a single unit, led by Major Weems.

Potter sends for Sidney Freedman when he loses confidence in his surgical abilities, and Winchester loses patience with his bunkmates' sloppiness.

Winchester, Pierce, and Hunnicutt find themselves in the sticky position of having to decide which enlisted men to recommend for promotion. For Winchester it could be a matter of life and death.

It's Halloween at the 4077th, and the staff dons costumes and trade ghost stories. Father Mulcahy discovers a soldier alive that had been pronounced dead.

The Army tries to get a North Korean pilot to defect, and Charles gets a rude shock when he falls for a French nurse with a Bohemian past.

Posing the theory that people will believe in anything, Charles and Hawkeye start a rumor that Marilyn Monroe plans to visit the 4077th, which gets everyone excited.

How can I ever look at a pair of shoes again without thinking of him?"
