"To Market, to Market" is the second episode of M*A*S*H. It was first aired on September 24, 1972 and repeated on April 29, 1973. Like many other M*A*S*H episodes, this one parodies army bureaucracy.

Thieves hold up a truck load of medical supplies for the 4077, thus rendering them in desperate need of Hydrocortisone. In retaliation, Hawkeye and Trapper meet with a notorious black marketer, hoping to get some replacements. When they realize they have nothing reasonable to trade with him, they go to drastic measures to get what they need.

Frank Burns complains about Hawkeye Pierce's disrespect...and Henry appoints Hawkeye chief surgeon, to Burns's shock. The rest of the 4077th "coronates" Hawk while Frank and Hot Lips complain to General Barker. The General's visit provides him with a view of life at the 4077th M*A*S*H unit: camp hijinks, a poker game, and a surgery session. This shows him M*A*S*H has fun but gets the job done.

Sergeant Baker arrives at the camp with his Moose. Hawkeye decides to find a way of getting her away from Baker. He tries ordering him to release her, tries buying her, and then resorts to cheating at cards. He releases her but she won't go, so he tries to teach her how to be independent.

When Henry goes for some R&R, Hawkeye pretends to crack up so that Frank will let him and Trapper go on some R&R.

John Hodges, a chopper pilot referred to as The Cowboy because of his gun holster belt and cowboy hat, has been hit in the shoulder, and arrives at the 4077th. He is expecting a letter--he's worried his wife Jean at home is leaving him for another man ("She's probably off with some rodeo rider; she's a sucker for a 10-gallon hat!"). He wants to go home, but Henry refuses, stating Cowboy's wound isn't serious enough to merit a stateside ticket. Bad luck then follows Henry Blake like the seat of his pants: he gets shot at while golfing, his tent gets flattened by a driverless jeep, and the latrine explodes while he's inside. The Cowboy offers to fly Henry to Seoul and then threatens to shove him out! The letter finally arives for Cowboy, assuring he is loved. Hawkeye and Trapper uses the radio to convince The Cowboy to spare Henry's life and come down, at which they succeed.

Hawkeye writes home, describing Christmas in Korea: Radar ships a jeep home, a piece at a time; Henry gives the monthly lecture on sex, with the aid of figure A and figure B; Trapper helps deliver a calf; Klinger and Frank get into a fight, but Father Mulcahy smoothes things over; Hawkeye and Trapper sabotage Margaret's tent; Hawkeye flies to the front line dressed as Santa, to help a wounded soldier.

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...!

Once again, Hawkeye writes home to his father, telling him of the latest gossip: the camp gets a new surgeon, who turns out to be a fake; Hawkeye bets he can walk into the mess tent naked for lunch, and no one will notice; Radar cheats on his final exam from the High School diploma company; Margaret rejects Franks advances and he gets drunk late into the night; the camp have a no talent night.

The camp suffers from the severe cold, except for Hawkeye who has received some long john's from his father. They get passed around from person to person, as a gift, a gambling stake, a trade, a bribe, stolen, given up to Father Mulcahy, who gives them to Henry, who returns them to Hawkeye as thanks for taking out his appendix.

As usual Frank's normal drone of verbal abuse upsets Ginger, so Hawkeye puts his arm in a cast while he is asleep. Frank puts in for a transfer, and after a broadcast goes out of Frank telling Margaret he's leaving, she decides to leave as well. As a result, Col. Blake puts both Hawk and Trap on double post-op duty until he finds replacements for Majs. Burns and Houlihan.

Unwilling to lose their two favorite patsies, and to be worn to a frazzle from doing 2 shifts in O/R, Hawkeye and Trapper hatch a scheme to prevent Frank and Hot Lips from leaving. That night, Hawkeye and Trapper pretend they have found gold, letting Frank overhear them. Frank then withdraws his request when he thinks he's found gold himself, although the joke is on him when he finds, amongst other things, a gilded jeep!

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.

Captain Kaplan is to be shipped home, but becomes paranoid that something will happen to him before he leaves. He takes the wheel of the jeep to drive to Kimpo himself, but crashes and ends up in plaster. Henry's wife is in labor and gives birth while he has Radar calling the hospital every 5 mins.An entertainer, Jackie Flash, visits the camp to entertain the troops.

Brought on by Frank and Margaret's negative reports, General Clayton assigns a psychiatrist, Captain Hildebrand, to examine the 4077th M*A*S*H unit, to see if it should be disbanded. Henry tells them to be on their best behavior, or else they will be split up. But the 4077th soon begins to act in their traditional, insane ways: the shrink experiences Max Klinger, watches the hijinks of Hawkeye and Trapper John, and witnesses the trysts of Frank and Hot Lips. While Hildebrand confronts the unit on its behaviour, choppers bearing wounded begin to arrive and everyone heads for the OR. The onslaught of casualties shows the 4077th's true side.

An inept North Korean pilot, known as "5 O'Clock Charlie", makes his daily attempt to bomb the ammo dump. Frank puts in a request for an anti-aircraft gun, which is granted when Charlie hits General Clayton's jeep. Frank takes charge of the gun, while Hawkeye and Trapper are determined to prevent him using it, by getting rid of the ammo dump. Frank misses Charlie and destroys the dump.

Radar writes the weekly activity report. Hawkeye operates on a wounded prisoner who grabs a scalpel and attacks the doctors. Frank wants Klinger thrown out on a section 8,so Henry calls in a psychiatrist, Major Freedman. Hawkeye is attracted to a new nurse but thinks she is married. Trapper loses a patient who developed complications during the O.R. fracas with the wounded soldier.

Hawkeye and Trapper want the army to admit responsibility for the accidental bombing of a local village. They fill out a report and Major Stoner arrives to investigate, and leaves with all the evidence. When the story is released it claims that the enemy bombed the village, and the army tries to gag the doctors. But, thinking there could be a medal in it for him, Frank has also put a report together, with copies of all the evidence, including shell fragments, so the army comes clean.

Hawkeye has been in non-stop surgery for 3 straight days without sleep, and the wounded keep coming. He decides to find out who started the war, and sends a telegram to Harry S Truman. After listening to some of Frank's rubbish about the North Koreans wanting better plumbing, he tries to send the officers' latrine to the North Koreans with an offer of peace. Trapper finally manages to sedate him. Trapper (about Hawkeye): "I guess he's just unstable. You see, he took this weird oath as a young man, never to just stand by and watch people die."

Hawkeye operates on a 5-year old Korean boy, and Radar can't find his family. Henry plans to send him to the orphanage, and the camp enjoys his company while they can. Trapper decides to adopt him after consulting his wife, and has to rescue him after he wanders into the minefield. Kim's mother turns up at the orphanage looking for him.

Corporal Walker is being sent home, and he wants to marry his Korean girl so she and their baby can return with him. CID sends Lt Willis to investigate, but when he refuses Hawkeye and Trapper frame him. Hawkeye is upset that a nurse he was pursuing does not approve of the marriage between "a gook" and "one of us".

Majors Houlihan and Burns press charges against Colonel Blake to get him arrested and put Frank in charge, and put Hawkeye and trapper under arrest so that they can't help him. Fortunately for Henry, they escape, and with the aid of Meg Cratty come to the rescue.

A lone sniper has the 4077th pinned down - including Radar and Henry in the shower. The poor boy thinks he's firing on McArthur's headquarters, and a chopper finally comes by and wounds him with gunfire from above, ending the siege. Hawkeye walks out to into the bush to tend to the wounded soldier.

The camp succumbs to the Asian flu, except for Hawkeye and Margaret, who have to do everything themselves. As the others start to recover, Hawkeye falls ill but he still manages to operate when wounded arrive. Finally the others are well enough for Hawkeye to stop working and rest. He is thanked for his service with a commemorative roll of toilet paper.

Hawkeye and Trapper recover from an all night party. Henry gets a barbecue, and Hawkeye puts in a request for an incubator. The Quartermaster turns him down. They locate a Major with 3 incubators, but he won't let them have one. A Colonel tries to sell them one, and then they get into trouble with a General at a press conference. Finally, Radar trades the barbecue for an incubator.

The 4077th and friends convene for their weekly “Medical Conference,” A.K.A. Poker while Radar runs over a civilian and Frank is held hostage in the showers by an enlisted man.

Hot Lips gets depressed and requests a transfer, causing turmoil in the camp.

Klinger pretends to be pregnant. Hawkeye and Trapper operate on General Mitchell's son, and the General gives them 3 days in Tokyo Henry keeps getting calls from Tokyo about what Hawkeye and Trapper are doing. When they get back to the 4077 Frank asked the general for an officers club for the camp. They plot to allow the enlisted men access to the club, and when the General opens it the rules are bent to give his son access, which Hawkeye exploits to give access to all.

Henry returns from a week in Tokyo, to announce that he is in love with a 20-year old girl called Nancy Sue Parker. She arrives for the weekend, and Henry shows her off. Nancy comes on to Hawkeye while Henry is in surgery. Henry is reminded of his wife back home when Radar places a call for him, and he realises it's his wife he loves.

A riotous episode in which Hawkeye will do anything to get a new pair of boots: In order to get Zale to get him some, he must get an appointment for Zale with Futterman, the camp dentist, who will only do it if Henry will give him a pass to Tokyo, and Henry will only grant the pass if Houlihan will get off his back, which she will do only if the guys throw a party for Frank's birthday, with a cake, and Radar will only help get the cake if he gets a date with Nurse Murphy, who will only date someone with a hair dryer, and Klinger won't give up the hair dryer unless he gets a section 8 (and Frank won't sign). Inevitably, the deal falls through, much to the Hawkeye's chagrin.

Private Baker, who is always going AWOL, is desperate for plastic surgery on his nose. Hawkeye gets an old friend, and plastic surgeon, to visit the camp, promising him a nurse called "The Barracuda". They put together an elaborate scheme to perform the operation without Frank or Margaret finding out.

A Korean family set up camp in the middle of the compound. A Korean woman with a baby comes looking for the father, and names Radar. Civilian affairs relocates the family and blood tests prove Radar is not the father.

While there are no casualties, Hawkeye & Trapper crate up Frank while he sleeps and receive gorilla suits through the mail. Henry gets a tan and gives another sex orientation lecture. When the wounded start pouring in again, their own side shells the camp, hitting the generator, and Radar tries to get through to someone to stop the shelling.
