Season three opens the door to learn more about Klaus and the Original Family as his motives for wanting Stefan on his side are finally revealed. As Stefan sinks deeper into the dark side, Damon and Elena struggle with the guilt of their growing bond, even as they work together to bring Stefan back from the edge.

This season, Katherine's appearance in Mystic Falls will throw a wrench into the love triangle between Stefan, Elena and Damon, and the other residents of Mystic Falls must choose sides as they fall victim to a new breed of danger. New and unexpected friendships will be forged, allies will become enemies and hearts will be broken. Plus, Stefan and Damon will be forced to face a villain more evil and diabolical than they thought possible.

The year is 2048, and global warming has flooded much of Earth's land areas. A father and his two sons try to salvage treasures from sunken buildings when they are given an important assignment by the New Vatican.

Life hasn't been the same for Elena since the tragic death of her parents, but she tries to pick up the pieces and provide support for her troubled younger brother, Jeremy. On her first day back at Mystic Falls High School, Elena meets the mysterious new guy, Stefan, and the two seeming lost souls form an instant connection. What Elena doesn't know, however, is that Stefan is a vampire, constantly resisting the urge to taste her blood. But Stefan, it seems, has a greater evil to deal with when his dangerous older brother, Damon, shows up to wreak havoc on the town of Mystic Falls — and claim Elena for himself.
