Captain Carter was part of the Avengers in the Battle of New York.
Bucky Barnes is the American Secretary of State but he finds himself in danger.
What if Steve Rogers had not died. That he was alive and became a Hydra stomper after getting brainwashed.
Bucky tries to get through Steve, knowing Steve would do the same if the positions were reversed.
Captain Carter and the Black Widow try to somehow salvage the old Steve in a safe house in St Kilda in Scotland. His suit is keeping Steve alive who has barely aged over the years.
Eventually both women discover that this was all a ploy by Melina Vostokoff. She arrives with her Red Room academy. Melina's beef is with Captain Carter and the Black Widow.
This is very much an alternate take on Captain America: The Winter Soldier as well as the Black Widow movie. It is good to see both women uniting and it seems there is more to come from Captain Carter.
