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.

When Freddy Lupin's wayward wish transforms him into a werewolf and deposits a mischievous moon sprite on Earth, Freddy must restore the cosmic order before the earth and moon collide.
