April-May 1953: China has made an incredible offer, to return a handful of prisoners of war too wounded for their own medical facilities. After some debate about the Chinese motives, Hawkeye, Trapper, Frank, Radar and Klinger take a bus deep into North Korea to an agreed-upon meeting place called "Rainbow Bridge" to receive the prisoners, but Major Burns decides to bring a gun, in violation of the agreement. Tensions are defused when the gun is only about as big as a cigarette lighter.
