A man falls under the power of an ancient spell and is transformed into a sheepdog.
It all begins when workaholic Deputy D.A. Dave Douglas (Allen) takes on a case involving an animal laboratory - one that will take him away yet again from his wife (Davis) and kids (Grey and Breslin), who already yearn for his all-too-distracted attention. But when Dave is accidentally infected with a top-secret, genetic-mutation serum, everything he thought he knew about being himself and his family changes. Yet with his newly perked-up ears, and his front-row seat on the household carpet, Dave is able to gain a whole new perspective into his family's secrets and dreams. Now, he wants nothing more than to stop fetching and return to fathering - only first he'll have to stop the evil forces behind the serum.
