The plot description continues:

Eventually, the odd investigation leads Peggy to quirky yet charming scientist Jason Wilkes (Reggie Austin), who quickly becomes an ally — and sparks fly. As Peggy continues to find clues in this peculiar case, she is introduced to the machinations of Whitney Frost (Wynn Everett), a movie starlet, brilliant physicist and the true power behind husband and senatorial candidate Calvin Chadwick (Currie Graham). Calvin, a politician who will do anything to get to the top, befriends Vernon Masters (Kurtwood Smith), a veteran of the War Department with a keen understanding of how to work the system. Peggy soon discovers that corruption seemingly runs deep, making it hard to distinguish the good versus the bad.

The search comes full circle when Russian spy Dottie Underwood (Bridget Regan) returns into Peggy's life in a new and unexpected way. But even as Peggy discovers a new city, both old and new friends – and potentially a new love – she's about to learn the bright lights of post-war Hollywood mask a more sinister threat to everyone she is sworn to protect.

Executive producer Michele Fazekas dished on the new villain this season in an interview with Entertainment Weekly. Fazekas revealed: "The big bad is Whitney Frost, who's played by Wynn Everett. What I like about how we told the story this season is that we see her from the beginning. We see her go from just a person who's manipulative. The relationship she has with her husband is more of a Lady Macbeth, where she's manipulative, a genius who operates from behind the scenes. You see her become a villain. We also tell some of her backstory in episode 4."

"We actually compare and contrast her and Peggy, like how do these two women, who are similar in many ways — they're both very smart, strong women — end up in very different places in their life," she shared.
