Ep 4. The Blitzkrieg Button

Peggy Carter is still reeling from the news that her friend and colleague Howard Stark is a traitor, wanted by the US government for selling deadly weapons to the highest bidder. In The Blitzkrieg Button, Agent Carter must juggle her professional duties as a member of the Strategic Scientific Reserve (SSR) with her ongoing efforts to clear Stark's name and restore his reputation.

As the episode opens, Peggy witnesses a hooded figure breaking into her apartment and making off with one of Stark's inventions - a device that he called "the Blitzkrieg Button." This small, mysterious object seems to be of great importance to both Stark and his enemies, and Peggy sets out to track down the thief and recover the device before it falls into the wrong hands.

Meanwhile, the SSR is investigating a string of apparent suicides among members of a top-secret program called the Battle of Finow - a highly classified experiment in which soldiers were exposed to a dangerous gas that was supposed to make them invincible. Peggy quickly realizes that the two investigations are connected, and she believes that the Blitzkrieg Button may hold the key to understanding what really happened at Finow.

With the help of her SSR colleagues - including the bumbling but well-meaning Agent Sousa and the icy Chief Dooley - Peggy begins to unravel the mystery behind the Battle of Finow. As she learns more about the dark history of the program, she realizes that she may be dealing with something far more sinister than mere scientific experimentation - something that could have catastrophic consequences for all of humanity.

Along the way, Peggy must also contend with the personal toll that her work is taking on her. As a woman in a male-dominated field, she faces constant sexism and condescension from her colleagues, even as she proves herself time and again as a skilled and resourceful agent. She also wrestles with her feelings for her former flame, Captain America, and wonders what might have been if he had survived the war.

In the end, The Blitzkrieg Button is a thrilling and suspenseful episode that raises the stakes for Peggy and her allies. It sets the stage for a complex and multifaceted mystery that will keep viewers on the edge of their seats, as Peggy fights to clear Howard Stark's name and expose the truth about the Battle of Finow. With compelling characters, high-stakes drama, and plenty of action-packed thrills, Agent Carter is a must-see show for fans of the Marvel universe and anyone who loves a good espionage thriller.
