As the summit fast approaches, Elizabeth enlists Philip’s help for a mission that could yield game-changing intel.
Marilyn and Norm locate both Gennadi and Sofia, who are living separately, by following Stan. Sofia tells Stan that she and her son Ilya want to be reunited with Gennadi. Claudia and Elizabeth tell Paige about World War II from a Russian perspective. Using a surveillance picture taken by Paige, Claudia identifies a CIA officer from the Soviet Division meeting with Nesterenko, along with a high level staffer from senator Sam Nunn's office.
Elizabeth sleeps with Philip and, in the morning, asks Philip to go to Greece with Kimmy and take her to Bulgaria, where she will be arrested with (planted) drugs (in more of a kidnapping) to blackmail her father about Nesterenko. Elizabeth approaches Gennadi on his way back to his safe house, but just as she reaches him, his bodyguard shows up, and she walks away. Stan suggests to Renee that she could work in the FBI personnel office. At a campus bar, Paige meets a boy who tries to pick her up, until his rude friend starts insulting her. When she starts to leave,the rude friend grabs her, and she beats him up, then punches the boy in the nose when he follows her. "Jim" (Philip) meets Kimmy in Ann Arbor, but she isn't enthusiastic about meeting him in Greece. To change her opinion, "Jim" and Kimmy make love. "Stephanie" gets another art lesson from Erica. Tatiana locates Oleg at class and blames him for William's capture in 1984, which cost her a promotion and stalled her career. She then has the new KGB rezident notify the Center that Oleg is in the U.S. and is not loyal.
Paige comes over to her parents' house for a sparring session and tells them both about the bar fight and Brian. Elizabeth tells Philip that Paige may not be cut out for spying; Philip states that she can do it but shouldn't. Philip visits Paige's apartment to discuss the bar fight. When Paige tells him that she likes spying, he challenges her to spar and gets her in a chokehold she cannot break, releasing her just before suffocation. Elizabeth climbs the fire escape to break in to Gennadi's and unexpectedly finds Sofia there visiting; she kills both Gennadi and Sofia, leaving 7-year-old Ilya alive. Claudia and Elizabeth teach Paige to drink olive oil first to be able to consume more alcohol, and then they all test their drinking capacity by getting drunk on vodka. Over a beer, a crushed Stan tells Philip about the murdered couple and their orphaned son, who found his parents covered in blood. After Stan leaves, Philip calls Kimmy to cancel "Jim's" trip to Greece and to break up with her, and then tells her not to visit a communist country while in Europe.
The episode takes its name from the war fought between the Soviets, Nazi Germany and its allies, which took place from 22 June 1941 to May 1945.
