S01E01 Teen Wolf's Family Secret
The grandmother of Scott finds the old family album, like Scott his ancestors also had the ability to turn into werewolf every full moon.
The Howard family starts acting crazy and more feral than usual among turning into werewolves, and the cause is eventually linked to Lupe's science project.
Like all teens growing up, Scott Howard is going through some changes. Only, compared to the other kids in Wolverton, Scott's changes are a little odd: long hair, sharp nails and...fangs! Scott is a werewolf! As if Scott didn't worry about being accepted by his schoolmates enough! But as hairy as things can get for a budding werewolf, Scott's friends and the other members of the Howard family will be there to help him through it.
