The 4077th is designated as the setting for the making of an army film on Mobile Army Surgical Hospital units. Hawkeye is chosen as the star while Margaret and Frank compose a screenplay. The Eye Of The Hawk objects to the piece of propaganda that filmmaker Lt. Bricker is producing and, having exposed the original film, reshoots a new one his way, starring himself as Groucho Marx-ish Yankee Doodle Doctor, and poking fun at glorifying doctors while concluding with a rather serious speech about the hell of war.

Hawkeye creates a fake doctor, Captain Jonathan S. Tuttle, to give supplies to the local orphans. Henry wants Tuttle to be officer of the day, so Hawkeye creates a fake personnel file, and all his back pay is given to the orphanage. When General Clayton wants to reward his generosity, Hawkeye is forced to invent a story about Tuttle jumping from a chopper without his parachute! Of course, Trapper's new friend, Captain Murdoch, obtained the fake dog tags and parachute...!

General Clayton calls to say that a ceasefire is to be declared. The camp celebrates, Klinger gives away his dresses and locals start to take pieces of the camp. But Trapper does not believe it. Hawkeye claims he is married to avoid promises he made to several nurses. The party to celebrate the cease-fire, which never really took place, is interrupted by incoming wounded.

Gen. Clayton sends a psychiatrist to the 4077th to gauge the camp's cohesiveness and fitness as a unit.

An inept, if punctual, bomber pilot provides comic relief for Hawkeye and Trapper, but inspires Frank to call out the heavy artillery.

Hawkeye and Trapper receive high-level flak when they buck the brass to report the "friendly fire" shelling of a South Korean village.

Hawkeye has been operating so long he just can't quit, and he decides to try to end the war while he's at it.
