As the fifth season opens, the Chinese are getting too close for comfort and the 4077 has been ordered to bug-out. Unfortunately, Hawkeye, B.J. and Margaret are in the middle of critical surgery and have to keep going even as the bombing starts. The rest of the 4077 find themselves in an equally dangerous situation upon discovering that the new location that HQ has chosen for them is actually in occupied territory. Luckily the Chinese are driven back and the 4077 get to bug back to their old location. But the real bomb, as far as Frank Burns is concerned, is when Margaret returns from a medical conference in Tokyo engaged to Lieutenant Colonel Donald Penobscott. "How’d Burns take it?" a concerned Colonel Potter asked. "Hard," Hawkeye replied. "He was clucking like a chicken last night. For nine straight hours." Potter shook his head. "He’s heading for a Section Eight." As expected, Klinger was green with envy.
