Teen Wolf

A bizarre night in the woods seems to improve nerdy high schooler Scott McCall's life, but his disturbing symptoms and a warning from a mysterious stranger portend dark times ahead.

Struggling to control his werewolf transformations, Scott worries that playing in an upcoming lacrosse game is too risky, and Stiles sets out to prove Derek's guilt in a recent murder.

Afraid he might have unknowingly committed a violent act, Scott embarks on a double date with Allison, Lydia and Jackson -- and receives shocking news from Derek about his fateful bite.

Derek's encounter with a formidable new hunter leaves him close to death, and before Scott and Stiles can save him, Scott must navigate an awkward dinner with the Argents.

Another violent death leaves Jackson and Lydia traumatized, and Scott is blissfully unaware of Derek's perilous situation with Kate as he and Allison cut school to celebrate her birthday.

Allison learns some intriguing details about her ancestors, and Scott works to control his temper -- and therefore his transformations -- with help from both Stiles and Derek.

Stiles, Scott, Lydia, Jackson and Allison begin to distrust one another as they spend a terrifying night trapped in the high school, stalked by the vengeful alpha werewolf.

Scott's family and friends are alarmed when the full moon brings out his dark and vengeful side, and Jackson, Chris and Kate begin to draw conclusions about the monsters' identities.

A power-hungry Jackson forces Scott into a dangerous bargain, Lydia receives some unpleasant news, and Stiles and Derek make a shocking discovery about the mysterious alpha.

Kate brings a wary Allison into the family secret, Scott meets a new adversary and an unexpected ally, and Jackson's ruthless ambition places him in mortal danger.

Derek and Kate's twisted past is revealed, Allison reels from another huge revelation, and the school's winter formal turns tragic as Peter and the werewolf hunters close in on their prey.

Stiles tries to outwit Peter and save his friends, Scott teams up with Derek to take down the alpha for good, and Allison learns the importance of her hunter family's strict moral code.
