The Pack is horrified to see the latest wolf kill is a little boy. A group of hunters come upon the scene and start accusing the Pack of being sketchy, given this is the second woif kill on their land. Also, Elena subtly barks at a hunter's dog.
After receiving flowers from Philip, Elena confides to Jeremy all about her human boyfriend. Jeremy warns her that the truth always comes out (i.e. he's gonna find out she's a werewolf sooner or later).
Elena and Clay look for the psycho wolf but find that townsfolk blame them (and everyone from stately Stonehaven Manor) for all the wolf deaths, or at least think they know more than they are saying.
Nick, Logan and Pete arrive at a weirdly abandoned pool hall/warehouse thing to meet with Karl Marsten, a free agent werewolf. They hope he can give them intel on the identity of the killer wolf.
Elena and Clay track the killer wolf, Brandon, to some rave/nightclub place. Elena confronts him, but Brandon begins transforming into his lupine form.
As a wolf, Brandon goes on a rampage and kills many ravers (Important moral on the dangers of raves - you could get killed by a wolf).
The local Sheriff pumps wolf Brandon full of hot lead and he does.
Clay and Elena find a raver who was bitten, and will become a werewolf. Clay realizes he's a heroin addict, so he mercy kills him - explaining to a disapproving Elena that his drug addiction means he'd have never survived the change.
Another death is too much for Elena, who hightails it back to Canada and Philip. They knock boots and all seems well.
Except it's not. Elena gets a call from Jeremy - Pete, the rocker dude werewolf that's part of the Pack - is found dead. But whodunnit?
