Everything starts off in the O.R. with Frank up to his usual antics in the O.R. Including harassing the nurses. After the O.R. session, Henry receives a message from General Hammond. It appears the 4077th has acheived a 90% officiency rating. The best of any medical unit in Korea. Later, as Henry is receiving the award for the unit and makes an attempt at a speach. Which is cut short by the General who announces the Henry's experience is needed elsewhere and that he's being reassigned to Tokyo. And unfortunately for everyone else...with Henry gone, that leaves Frank Burns to take over command of the outfit. And Frank wastes no time in moving his things in to Henry's old tent.
The next morning, Hawkeye, Trapper, and Spearchucker are awoken to a bugle playing Reveille. They are then made to suffer through morning calisthenics. And a surprise tent inspection where Frank orders the still removed by an MP. That's the final straw, and they come to the decision that Frank has got to go.
A whole group meets in the Mess Tent and come to the decision that the answer to their problems is to get Henry back in command. Radar scrounges up a couple of passes to Tokyo so Hawkeye and Trapper can go see Henry.
In Tokyo, they initially try to get Henry to come back be telling him how bad Frank is running things into the ground back at the 4077th. But Henry's not buying it. That is, until Hawkeye gets a call from the 4077th. Radar fakes a serious illness and Hawkeye and Trapper let word of this "illness" slip so that Henry overhears. They claim to not be able to figure out what's wrong with him. So Henry decides to fly back to the 4077th to try to find out what's wrong with Radar.
Back at the 4077th, Henry is examining Radar and Radar is doing his best to act gravely ill. Frank comes in and demands Henry fill out paperwork before examining any patients, Henry tells him to "Stuff it." The plan goes well until Henry decides he has to do an exploratory on Radar. Radar panics. Frank objects to the idea. And Henry threatens to go over his head and call General Hammond. Radar hears this, jumps up, and offers to call General Hammond and runs over to the phone.
The plan is blown because Radar is obviously fine, but Hawkeye explains. Frank is angry and threatens to call the MP's. Henry cancels his order and announces he's back in commmand.
The show ends with Hawkeye, Trapper, Spearchucker, Radar and others playing cards in the Swamp when Henry comes in and announces that he's back, but "no more horsing around". Then he joins the rest of them for a drink.
