This January, journey to the Marvel Universe of the 1950s for an all-new globetrotting adventure in OPERATION S.I.N. #1, the blockbuster new limited series from fan-favorite writer Kathryn Immonen and artist Rich Ellis! Tying in to the explosive events of Original Sin, OPERATON S.I.N. tells an untold story of the origins of the Marvel Universe starring Peggy Carter, Howard Star and Woodrow McCord!

At the height of the Cold War, a supremely powerful alien energy source is discovered on Russian soil. In an effort to prevent it from falling into the wrong hands, secret agent Peggy Carter and Howard Stark must intercept it before it’s too late. Only they’re not the only interested parties…

A new terrorist splinter group named Hydra is on the hunt, seeking the alien technology for their own sinister purposes. It’s only when a mysterious operative named Woodrow McCord enters the picture that Peggy and Howard will see just how far some people will go to keep Earth safe from harm. But is he there to aid Peggy and Howard? Or to stop them?

“To me, there was no one else that could handle this story with as much finesse and style as Kathryn and Rich,” says series editor Jon Moisan, in an interview with Marvel.com. “There was no one else in my mind that would write it as well as Kathryn.”

Explore Marvel history like you’ve never seen it before as Peggy Carter, Howard Stark and Woodrow McCord do battle against the rising forces of Hydra. The Cold War spy espionage adventure kicks off this when OPERATION S.I.N. #1 explodes into comic shops and digital devices this January!
