In the series premiere, years before Agent Coulson and his S.H.I.E.L.D. team swore to protect those who cannot protect themselves from threats they cannot conceive, there was Agent Peggy Carter, who pledged the same oath but lived in a different time when women weren't recognized as being as smart or as tough as their male counterparts.

Howard Stark's deadliest weapon has fallen into enemy hands, and only Agent Carter can recover it. But can she do so before her undercover mission is discovered by SSR Chief Dooley and Agent Thompson?

As Agent Carter closes in on Howard Stark's stolen technology, Peggy's secret mission could unravel when the SSR arrests Jarvis, and a secret is revealed.

Peggy may be in more trouble than usual when fugitive Howard Stark suddenly returns for mysterious reasons. And Chief Dooley chases a new clue all the way to Europe that threatens to destroy Peggy's future at the SSR.

Peggy is finally trusted with a mission and calls upon her trusted Howling Commandos squad for backup. But her cover could be at risk when SSR Chief Dooley also sends Agent Thompson with her.

Peggy discovers the shocking truth about Leviathan but doesn't realize that her true enemies are even closer than she imagined. Meanwhile, Souza is close to confirming the truth about Peggy and may just put her in the crosshairs of the SSR.
