A supernatural thriller about the lone female werewolf in existence begins when Elena is forced to leave the perfect life she has made for herself as a photographer in Toronto to return to Upstate New York after her wolf pack is threatened.

Old feelings come to surface for Elena and Clay, who find themselves in a dangerous situation when they track the Mutt to a warehouse and he turns into a wolf.

Elena and Clay deal with their growing sexual tension as they work together to figure out the who and why behind the plot to turn psychotic killers into werewolves.

Elena is overwhelmed with memories of her romance with Clay, including the day she was bitten by a werewolf, as she defends him against murder accusations; at the same time, Clay's character is put into question when former Pack member Daniel Santos shows up with information on the Mutt uprising.

Elena returns to Toronto, but her human life with Philip is interrupted when Santos arrives with a way out of the Pack. Elsewhere, at Stonehaven, Jeremy must fight to keep his Alpha status in tact.

Daniel Santos, the recently revealed leader of the Mutt uprising, wants to sit down with the Pack and discuss a truce. But are they just walking into a trap?

A poisoned Jeremy grows weaker by the hour as Elena and Clay race against the clock to save his life, but run into hurdles as they interrogate a Mutt and contend with a werewolf wannabe.

The Pack push personal issues aside to focus on survival after Santos sics a notorious killer on them, but Elena's feelings for Clay race to the surface after her own close call with death.

Elena returns to Toronto for her art show accompanied by Clay, who keeps a protective watch over her while camping out on Philip's couch. Elsewhere, the Pack receive valuable information about the Mutts from an unexpected source.

Elena enters into damage-control mode with Philip, who has become painfully aware of her romantic history with Clay; and later, breaks Pack law when the Mutts launch a coordinated attack in Toronto and threaten the human she loves.

Elena goes against her Alpha's commands when she embraces her killer instinct to free Clay from captivity. Later, when confronted by Phillip, she's forced to come to terms with her true identity.

In the Season 1 finale, Elena returns to Stonehaven and her Pack after learning the truth about Clay's role in her werewolf origins. Reunited, they ready themselves for an epic war against the Mutt army led by Santos and the mysterious James Williams.
