Members of the 4077th Mobile Army Surgical Hospital care for the injured during the Korean War and use humor to escape from the horror and depression of the situation. Among the 4077's people are Capts. Benjamin "Hawkeye" Pierce and "Trapper John" McIntire, Majs. Margaret "Hot Lips" Houlihan and Frank Burns, and Cpl. Walter "Radar" O'Reilly.

Three United Nations delegates visit: a physician who is similar to Charles, an Army officer who teaches yoga and a Swede who catches Margaret's attention.

Charles refuses to solve his annoying snoring problem; Potter's son-in-law visits with some shocking news.

A gruff general visits his severely injured son and faces the harsh realities of military life when the young man dies.

Hawkeye tangles with a tough Army colonel; B.J. helps a GI who has received a Dear John letter.
