Teen Wolf may have started as a reimagining of the film of the same name, but it's easy to tell very early on that it was a lot different than it's predecessor. The story follows werewolf Scott McCall (Tyler Posey), as he learns what it means to be a werewolf, and deals with all the problems it creates, including having to hide his relationship with Allison Argent (Crystal Reed) from her family, who happen to be werewolf hunters.
The second season focuses on the new supernatural threat, the Kanima, who can paralyze victims with the toxin in its nails. Scott and his friends try to figure out who the new creature is, as well as who is directing it to kill, all while also dealing with whatever is going on with Lydia, new werewolves, and a new werewolf hunter, who is even more of a threat than they have encountered previously.
