The series revolves around Scott McCall, a high school student at Beacon Hills. Scott's life changes dramatically when he is bitten by a werewolf the night before he starts his second year of high school, becoming one of them. He has to learn from now on how to balance his new problematic identity with the daily life of adolescence.

 Scott and his best friend Stiles Stilinski begin to meet other characters with a connection to the supernatural happenings in Beacon Hills. His main interest is Allison Argent, a classmate with Scott, who comes from a family of wandering werewolves. Her best friend is Lydia Martin, who finds out late that she is a banshee. Scott and Stiles are fighting Lydia's aggressive lover, local jock Jackson Whittemore, and Derek Hale, a mysterious werewolf with a dark past. As the show goes on, Scott is joined by new friends like Malia Tate, a werewolf coyote, Kira Yukimura, a Japanese kitesune and Liam Dunbar, a young werewolf with anger problems.

In the first three seasons, Scott is madly in love with Allison, but he is tainted by pain when she dies because of demons. Scott finds out he's a Truth Alpha.
My favorite characters in this series are; Isaac Lahey, Scott McCall, Malia Tate, Derek Hale, Aiden, Ethan and Liam.
