Having learned the truth about her werewolf origins, Elena reunites with the Pack to prepare for a final stand against the Mutts.

Frantic with worry, Elena disobeys Jeremy’s command and goes on a solo mission. Later, when Philip confronts her about who (or what) she is, Elena is forced to choose between her two worlds.

Elena attempts to rebuild her relationship with Philip after he learns that she hasn’t been entirely truthful with him. With the Pack divided on either side of the border, the Mutts make their move.

Elena’s worlds collide when Jeremy orders Clay to accompany her to Toronto for protection. An unexpected survivor is able to give the Pack valuable new information about the Mutts.

The pack must put personal issues aside when they’re faced with a new threat – one that has ties to the former Pack Alpha. Nick learns more about his father’s past. Logan is faced with a difficult decision when he receives an unexpected gift.

Jeremy has difficulty recovering from his injuries, forcing Clay to viciously interrogate a Mutt in the War Room, while Elena confronts a woman who wants nothing more than to be just like her.

The Pack accepts the Mutts’ offer to discuss a truce. But the meeting proves to be anything but what they were expecting. In Toronto, Philip reconnects with a former flame.

Back in Toronto, Elena’s commitment to Philip is tested and her life interrupted when Santos makes an unwelcome appearance. At Stonehaven, Jeremy’s title is challenged, forcing him to fight to maintain his status as the Alpha.

As Elena struggles to defend Clay against suspicions of murder, old memories of their past are stirred up. Former Pack member Daniel Santos arrives at Stonehaven with information about the Mutt uprising.

While tensions grow between Elena and Clay, Jeremy sends the pair to track a new Mutt threat. Their investigation reveals that this Mutt threat may be less random than they first thought.

Tension grows between the Pack and angry locals when another victim is discovered. Meanwhile, old chemistry resurfaces as Elena and Clay work together to track the killer Mutt to a warehouse rave.

At Stonehaven, Elena tracks the killer Mutt, while avoiding the advances of Clay Danvers, her former lover. Haunted by her own past as a killer, Elena is desperate to get back to her human life, but is delayed when a second body is discovered, this time on Stonehaven property.

After the mauled body of a girl shows up on the outskirts of Bear Valley in Upstate New York, Elena Michaels, the world's only female werewolf, is forced to choose between her new "human" life in Toronto with new love, Philip and her previous life with The Pack, at Stonehaven. Even though it's been a year since she abandoned her life among the werewolves, Elena still feels the sting of having forsaken her old world, while trying to build a new and "normal" life.
