There were no more super soldiers. It was a well known fact. But when Bucky retrieves a woman in cryostasis in an abandoned Hydra facility, he begins to wonder otherwise. She has a Vibranium spine, her history with Howard Stark and an oddly vague couple decades she refuses to depict.
Kate Alden was a scientist, engineer, and the next protégé of the 1950s until HYDRA deemed her necessary for their work. Being forced into Hydra's game, she is tasked with a nearly impossible mission: creating the Winter Soldier.
After thirty years in cryostasis, the one person that Kate thought she'd never see again was the one who pulled her out. Bucky Barnes. The person she thought she'd loved. Except, he had no memory of her her existence. He had no idea that she'd brainwashed, tortured and manipulated him for decades. He'd changed, he was good, and he had absolutely no idea what she had done to him. And it had to stay that way.
