Ep 1. Wolf Moon

In the first episode of Teen Wolf season 1, titled "Wolf Moon," we are introduced to the show's protagonist, Scott McCall (played by Tyler Posey), a high school student and lacrosse player living in the town of Beacon Hills, California. At the start of the episode, Scott and his best friend Stiles (played by Dylan O'Brien) are out in the woods looking for a dead body that is rumored to have been found in the area.

While searching, Scott encounters a large, wolf-like creature that attacks him and leaves him with mysterious bite marks on his side. The next day, Scott begins to notice strange changes happening to his body – he's suddenly faster, stronger, and more agile than ever before. He also develops an intense attraction to the new girl at school, Allison Argent (played by Crystal Reed).

As Scott tries to come to terms with his new abilities, he begins to suspect that he may have been bitten by a werewolf. His suspicions are confirmed when he meets Derek Hale (played by Tyler Hoechlin), a brooding loner who reveals that he too is a werewolf, and offers to help Scott navigate his new life as a supernatural being.

Meanwhile, Scott's good friend Stiles becomes convinced that the town's uptight and overbearing local sheriff, Stilinski (played by Linden Ashby), is hiding something about the recent attack in the woods. He also becomes infatuated with Allison's best friend, Lydia Martin (played by Holland Roden), despite her largely ignoring him.

As the episode unfolds, Scott grapples with his new identity as a werewolf, trying to keep his secret from his mother and the rest of the town while also dealing with the increasingly dangerous threats around him. Along the way, he learns more about the mysterious world of werewolves and other supernatural beings, and begins to uncover the truth about his own past and the events that led to his fateful encounter in the woods.

Overall, the first episode of Teen Wolf is a gripping and suspenseful introduction to the world of the show, setting up several intriguing plotlines and introducing a dynamic cast of characters. Fans of supernatural drama and coming-of-age stories will find plenty to enjoy in this exciting and action-packed series.
