A 2-hour reunion taking place 40 years after the show ended. It includes interviews with the surviving core cast members: Alan Alda (Capt. Benjamin Franklin "Hawkeye" Pierce), Gary Burghoff (Cpl. Walter Eugene "Radar" O'Reilly), Jamie Farr (Cpl. And later Sgt. Maxwell Q. Klinger), Mike Farrell (Capt. B.J. Hunnicutt) and Loretta Swit (Maj. Margaret "Hot Lips" Houlihan), as well as Executive producers Gene Reynolds and Burt Metcalfe.

In the closing days of the Korean War, the staff of the 4077 M*A*S*H Unit find themselves facing irrevocable changes in their lives.

Everyone steps forth with memorable contributions when Hot Lips insists that a time capsule be left by the 4077th crew.

When Charles is handed the job of being the 4077's charity collection officer, he desperately tries to pass the buck.

An old and dear friend of Col. Potter's arrives with injuries sustained in a careless accident.

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

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

Three U.N. delegates come to the 4077th and make a lasting impression on members of the camp, while B.J. treats a patient whose leg injury may require an amputation.

Father Mulcahy must save the camp's honor in a high-stakes footrace against the 8063rd. Hawkeye, BJ, and Hot Lips each bet on it. Meanwhile, Charles tries to help Private Walter Palmer, a patient who suffers frequent verbal abuse from his fellow soldiers due to a speech impediment.

Bored at the terrible film selection, Hawkeye and BJ try to get a copy of the notorious film, "The Moon is Blue." Wounded General Rothaker declares prohibition in camp.

Hawkeye receives a letter from Colonel Potters wife where she informs that she has paid the last mortgage on their home and asks Hawkeye and friends to throw a small surprise party for Potter to celebrate.

The whole 4077 are looking forward to a visit from Marilyn Monroe after a rumor starts; while B.J.'s fishing trip doesn't go as planned.

When a nurse that Hawkeye is dating dies, he offers to deliver her eulogy and discovers that he didn't know her. Klinger tries to interest Charles in a business venture.

It's another M*A*S*H prankathon. This time, Hawkeye appears to be the marked man after menial practical jokes happen to everyone in camp, but him. Will they get him too? Or is Hawkeye already the victim of an even larger practical joke?

Charles falls in love with a French Red Cross woman but realizes that their lifestyles are not compatible. Hawkeye and BJ are helping with an army PR stunt in their own way.

It's time for the annual 4077th Halloween party. Hawkeye is dressed as Superman, B.J. is a clown, Margaret is a geisha girl, Colonel Potter is a cowboy and Klinger is Al Capone. But it's not much of a party for the surgeons when unexpected wounded guests show up; Charles tries to help a slovenly marine who has a billiard ball stuck in his mouth; Father Mulcahy inadvertently saves a man's life when he is presumed dead.

The nurses return from evacuation to find that the doctors have left the camp a mess. Potter announces an inspection in two days, so Margaret and the nurses try to get everything reorganized. Nurse Kelly is mad at Hawkeye for ignoring her.
