As the eleventh season begins, rumours are running rampant around camp. One rumour has everyone believing that Marilyn Monroe is going to pay the 4077 a special visit, while another claims that the peace talks are finally making headway. This second rumour gets Margaret thinking after Charles mentions how a Los Angeles skyscraper had a time capsule built into its cornerstone. Although he thinks the idea is insane, Margaret decides to make a time capsule of her own to bury in camp. "We could put something in the ground to remind people we were here," she suggested. With Hawkeye's help, items from around camp were gathered up for the capsule: a chopper's broken fan belt, Radar's teddy bear, one of Henry Blake's fishing flies, a bottle of Charles's cognac and Father Mulcahy's boxing gloves.

And finally, the gang of the 4077 hears the announcement they've been waiting for:

"This is Robert Pierpoint speaking to you from nearby Panmunjom. It is one minute before ten p.m. We can still hear the sound of nearby artillery. At some point during the next few seconds, the guns should go silent, as the cease-fire officially goes into effect...

There it is. That's the sound of peace."
