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.

Maj. Reddish tries to bribe an injured North Korean pilot to defect; Charles falls in love with a Red Cross worker.

B.J. attempts to pull off the ultimate practical joke on Hawkeye.

A nurse who was close to Hawkeye is killed; Klinger tries to talk Charles into backing a business venture.

The 4077th receives two bottles of scotch for secret surgery and a tank to scare off snipers.
