I will post the Summary behind so you have a choice if you want to read it so your not spoiled! Enjoy

THE VAMPIRE DIARIES: Next season, the appearance of the villainous Katherine in Mystic Falls throws 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. Stefan and Damon will be forced to face a villain more evil and diabolical than they ever believed possible. And they’ll take their shirts off.  Frequently. Source
