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.

Mail call brings upsetting news to Father Mulcahy and a hint to Henry that his wife may be straying.

Frank decides alcohol has become a menace to the 4077th and declares total prohibition.

A possible attack causes nurses and patients to leave the camp.

Tired of the GI diet of liver and fish, Hawkeye calls Chicago for an order of ribs.
