Winter Soldier

A man with long dark hair and a metallic shoulder piece sits up in a dimly lit, high-tech room, looking distressed as he is connected to medical equipment; the scene cuts to a woman screaming while strapped into a machine with a helmet, with text overlays reading "WAKE UP," "THIS IS," and "NOT A HUMAN BEING;" the sequence ends with a shot of a man in a dark suit holding a mechanical arm, standing over a covered body with two other men in the background.
