The Plot:
After suffering a mysterious animal bite in the woods, Scott begins to experience strange symptoms including supersonic hearing and unusual bouts of rage. While investigating a local murder, Stiles puts the clues together to uncover Derek’s identity as a werewolf and suggests that he may have bitten Scott in the woods.
Enter Allison, the beautiful newcomer who steals Scott’s heart. The two quickly become an item before Scott realizes that Mr. Argent is actually a werewolf hunter. Allison doesn’t learn about her family history until later in the season, when her aunt enters the picture to help with the werewolf hunt.
Jackson suspects foul play when Scott’s lacrosse skills increase overnight. He eventually gets a taste of the werewolf powers for himself when the mysterious Alpha wolf scratches the back of his neck.

To Scott’s initial disbelief, Derek insists that he was not the wolf behind Scott’s bite, but that it was a lead wolf called an “Alpha.” The identity of the Alpha remains a mystery until Episode 9, when it is revealed that Derek’s burned uncle is the one behind the mysterious deaths that plague their town. As co-Beta wolves, Derek insists that he and Scott must work together to kill the Alpha. Allison’s aunt, who hints that she and Derek were previously involved in a relationship, eventually captures and tortures Derek.

Jackson and Lydia begin the series in a relationship, but breakup midway through the season. Allison breaks up with Scott as well, after which she and Jackson become close. She and Scott rekindle their romance at the winter dance, where he confesses his love to her.
Stiles eventually wins the attention of Lydia, whom he has long pined over, only to see her attacked by the Alpha outside the winter dance. At the same time, Scott’s identity is revealed to Allison as he transitions from teen to wolf in an attempt to save himself from being killed by two oncoming cars — one of which is driven by Mr. Argent.
