A year after Captain America "woke up" the Winter Soldier to his real identity, and now he is working for SHIELD, recovering himself and working to hunt down Hydra. Except now he has a personal babysitter in the form of Agent Rose Thorne, as most people at SHIELD don't trust him not to revert to his Winter Soldier persona.

(Immediately following the events of CA:TWS) He's lost. He can't trust anyone. Painful and confusing pieces of memories keep flashing through his mind. She's scared, because he's dangerous and unpredictable. But he needs her help to find out who he really is.
