داستان این انیمیشن روی شخصیتی به نام "فردی لوپین" که جانشینی برای خانواده اصیل گرگ نماها به حساب می آید، تمرکز دارد. اما اتفاقاتی در حال رخ دادن است که "فردی" را به شخصی کاملا دیوانه تبدیل میکند و Freddy Lupin, heir to a proud family line of werewolves, is in for a shock when on his 14th birthday his first 'warfing' goes awry, turning him into a ferocious poodle. The pack elders give Freddy until the next moonrise to prove he has the heart of a wolf, or risk being cast out forever. With the help of an unlikely ally in a streetwise stray named Batty, Freddy must prove he's 100% Wolf.
