A new "The Vampire Diaries" trailer video reveals that fans can look forward to an action-packed season, which includes frightening new villains, Caroline getting tortured, Stefan making out with a hot blonde (who may or may not be Caroline), and a fierce battle over Mystic Falls.

The promo video shows that the Salvatore brothers will run into major trouble, as Lily's (Annie Wersching) evil vampire-witch-hybrid Heretics try to take over Mystic Falls. As a result, Damon (Ian Somerhalder) and Stefan (Paul Wesley) will have to come up with a plan to defy their mother in order to get control of the town and prevent the Heretics from destroying all humanity.

"We don't mess with them, they don't mess with us," says Stefan to his brother, speaking of the deal they reached with Lily.

"We're making a huge mistake handing over our town to a bunch of supernatural terrorists?" Caroline (Candice Accola) asks Stefan, who is also aware of the poor life choices they're making.

"Yeah, probably," he responds.

In another clip, Bonnie (Kat Graham) seems to be working with Alaric (Matthew Davis), while Caroline seems to be going through some type of torture.

There is also a scene where Stefan is seen making out with a blonde, who is wearing a sunlight ring and looks a lot like Caroline from behind.

While speaking with Entertainment Weekly, executive producer Julie Plec gave a breakdown of what viewers can expect from the major characters on the show in season 7. She had the following to say of each.

Stefan: "Putting back on the hero hair." Damon: "Trying to deal." Bonnie: "Trying to help Damon deal." Caroline: "Lots of surprises in store." Matt: "Doing his best to protect and serve." Alaric: "Drinking." Enzo (Michael Malarkey): "Trying to find where he fits." Lily: "Trying to hold her family together." Tyler (Michael Trevino): "Gone. Missing. You will not only get a hint [of where he is] very early in the season, but you might even see his smiling face."

The season 7 premiere of "The Vampire Diaries" will air on Thursday, Oct. 8 at 8 p.m. EDT on The CW.
