With a North Korean air raid imminent, and the 4077th being unable to evacuate completely, female personnel are temporarily evacuated. This makes life hard both in and out of the operating room, and the doctors begin to realize what life without the nurses is like. The "air raid" (one plane, flown by Five O'Clock Charlie), only to drop insulting notes, with things like "Give up , Yankee Imperialist dog" arrives after a private screening of Frank's wedding film (without Frank's presence), and the nurses return home.
