Henry Blake is accused of aiding the enemy, and to prevent Hawkeye and Trapper John from getting evidence to exonerate him, Major Burns (in temporary command) confines them to quarters. Trapper and Hawkeye escape and go to the courtroom with proof that the North Koreans that Henry is accused of aiding were refugees and children at a civilian clinic near the border. Frank refuses to drop their charges, so Hawkeye and Trapper use what they know best to change his mind: blackmail.
