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.

Klinger and Father Mulcahy risk their lives to recover stolen medical supplies from a nearby bombed-out school.

Radar borrows Charles' record player and takes over as the M*A*S*H disc jockey.

Hawkeye and Charles set out to test the crew's gullibility when they announce that Marilyn Monroe is due to arrive.

Mildred writes a letter to Hawkeye; and a sergeant tries to kill the captive sniper responsible for his lieutenant's injuries.
