After Charles is nearly felled by a sniper's bullet, he develops a philosophical obsession with death. Meanwhile, the officers have all been assigned new responsibilities.

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.

Hawkeye is overcome by the devotion of a terminally ill G.I., who has leukemia, for his critically wounded buddy, but he has trouble coming to terms with the fact that he can't cure the man. Meanwhile, Father Mulcahy is worried about the impending visit of a Cardinal.

When Hawkeye can't stop a sneezing fit that has no apparent cause, psychiatrist Sidney Freedman digs into the surgeon's past for a clue to this unusual malady.

Colonel Potter nearly blows his stack when his well-intentioned colleagues mollycoddle him in order to lower his blood pressure.

One of Margaret's nurses tries to hide her severe drinking problem, and Hawkeye is scorned after a practical joke he plays on Winchester backfires.

Winchester is sent to inspect sanitary conditions on the frontlines, while the rest of the camp plans a surprise anniversary party for B.J.

Hawkeye wagers that he can go a full day without a wisecrack, and Winchester finally confronts the major who exiled him to the 4077th. Charles: "I will not, even for a return to that pearl of the Orient, Tokyo, lie to protect you while destroying a friend's career."

Klinger's army newspaper reports on Hawkeye's monument to military stupidity; a giant tower made from a half million erroneously shipped tongue depressors.

Margaret develops a case of prickly heat, Charles does his tax returns, and Klinger takes the P.A. apart - just some of the events, which occur during another unendurably, hot night at the 4077th.

Klinger saves Winchester's life when an explosion rocks the operating room; and B.J. is reluctant to reveal the extent of his injuries after the blast.

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.

Winchester takes command during Potter's absence; and B.J. and Hawkeye try to convince the Marines to grant a hardship discharge to an immigrant soldier, Private Jost Van Liter.

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.

On New Year's Eve, the staff looks back on the highlights of 1951: The doctors invent an artificial kidney machine; Mulcahy plants a garden; Margaret takes up knitting; and Klinger and Winchester bet on which baseball team will win the pennant.

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. Meanwhile, Winchester fulfills a family Christmas tradition but has trouble maintaining the anonymity required to keep it a truly charitable act. Even Klinger lends a hand.

Margaret has trouble pretending she's a chip off the old block when her dad, blood and guts "Howitzer" Al Houlihan, arrives for a visit. Also, Hawkeye fixes up a soldier who repays them with a large side of steak, but the general who it belongs to is really steamed.

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.

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."

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