Remember All Your Training, As We go to War

An abandoned Hydra base has been found. When the shield agents went and searched it along with Black Widow, they discovered something that they didn't expect to find there. A girl who was found frozen and forgotten.

Upon being brought back to Shield and defrosted, Black widow and Fury feel they found a helpful ally to help them take down Hydra. Only problem is, was she left behind on purpose or was she forgotten? This only proves to be a challenge to keep the young woman who was found safe once the Winter Soldier learns that the girl was found, and he won't stop until he gets what belongs to him back.

Will captain America, Director Fury and Black Widow be able to keep this young woman safe from the Winter Soldier; or will he get his hands on her again, and not let her escape his grasp again?
