The plot of this season is in line with the iconic events of the 1980s, including the release of the nuclear war movie "The Day After", former President Reagan's Star Wars speech, and David Copperfield's magical magic to make the Statue of Liberty "disappear". The core plot of the fourth season is "How does this Soviet spy family survive (how to protect themselves)?" At the same time, Nina, a double agent imprisoned in Russia, may return to the United States and reunite with her former lover Stan Beeman. Please note this "maybe", because no one can say for sure now. Henry, the youngest son of the Jennings family, has more appearance time this season. He often stays with his neighbor Stan in the first two episodes. Last season focused on Paige's changes. Maybe this season will focus on Henry's changes? In addition, Keri Russell's pregnancy will not be written into the plot. FX hinted that the show may end this season or in the fifth season.
