Klinger and BJ both have Radar related woes, causing them to go on a drinking binge. A drunken BJ becomes violent with Hawkeye.

Klinger discovers that his duties as company clerk include catering to the eccentric whims of the 4077th officers. Consequently, the unusual demands by Klinger's superiors leave little time to write a letter home to Toledo. Meanwhile, the Doctors are concerned about a young soldier who appears to be mentally deficient.

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.

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.

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

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.

Tired of reminders about Trapper John's skill as a practical joker, B.J. bets Hawkeye he can prank everyone present.

A military strategist refuses to accept responsibility for the war games that have mortally wounded his own son. And Margaret develops laryngitis, as she is about to meet her hero, Dr. Chesler.

Hawkeye is sent to a mental hospital; a freak accident causes Father Mulcahy to lose his hearing; Margaret worries about her post-war plans; Charles run across a band of Chinese musicians; BJ is sent home, much to Hawkeye's dismay; Klinger decides to stay in Korea to marry Soon-Lee; a ceasefire is declared, ending the war.
