A reality where S.H.I.E.L.D. agent Peggy Carter took the Super-Soldier Serum instead of Steve Rogers is turned upside down -- when the World War II hero is pulled from the ice where she was lost in action decades before! Now, Peggy struggles to find her footing in a modern world that's gotten a lot more complicated -- cities are louder, technology is smarter and enemies wear friendly faces. Everyone with an agenda wants Captain Carter on their side, but what does Peggy want? As she teams with S.T.R.I.K.E. to investigate the sudden resurgence of Hydra, something doesn't feel quite right. Can Peggy trust what she's being told, or is someone trying to use her as a high-profile pawn in a game she doesn't yet understand? This new Sentinel of Liberty is a shield-slinging sensation!
