Less than a month before its premiere, "Teen Wolf" season 3 has been previewed in a new trailer. Sharing more scenes from the upcoming chapter, it gives a look at what Scott is now dealing with: random killings and a new Alpha pack that he has to stop.

It becomes harder with Scott's emotional struggle as he thinks everytime he fights back, everyone is getting killed. Dr. Deaton advises him, "Don't stop them, lead them." Derek, meanwhile, is told to kill his own pack member.

The third season of the supernatural drama series will pick up four months after the events that nearly ended Jackson's life and resurrected Peter Hale's, when teen werewolf Scott McCall and his friends Stiles, Lydia and Allison begin their Junior year of high school unaware that a new threat has arrived in Beacon Hills.

A deadly pack of Alpha werewolves is intent on bringing Derek into their fold. In the season three premiere, a new Alpha Pack arrives to wreak havoc on Scott's life while Derek and Isaac struggle to locate Erica and Boyd.

Executive producer Jeff Davis recently teased about Derek's fate, "It'll be interesting to see where he ends up at the end of the season."

The show will return with the first half of its supersized 24-episode third season on Monday, June 3 at 10 P.M ET/PT on MTV. New cast members include Charlie Carver and Max Carver as twin Alpha werewolves; Gideon Emery as Deucalion, leader of the Alpha werewolves; Felisha Terrell as Kali, an Alpha werewolf; Brian Patrick Wade as Ennis, an Alpha werewolf who is a force of pure brutality; and Adelaide Kane as Cora, a tough 17-year-old who has ties to the Beacon Hills werewolf line.
