Comedy in which Tim Allen transforms from family dad to family dog. 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, Rebecca (Kristin Davis) and kids, Carly (Zena Grey) and Josh (Spencer 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.
