Sheriff Forbes (Marguerite MacIntyre) calls Damon (Ian Somerhalder) and Stefan (Paul Wesley) to the hospital, where someone has been attacking patients. Still trying to force Katherine (Elena Dobrev) to help her, Bonnie (Kat Graham) refuses to give up on her plan to defeat Silas. As a violent wind storm causes a power outage in Mystic Falls, ghosts suddenly appear - some with good intentions and some bent on revenge.
