Archie (Gary Busey) is a rich and utterly despicable practical joker. He is one week away from playing a CD-ROM that will change the lives of his trusted manager Dexter (Curtis Armstrong) and other employees forever, when he is suddenly involved in a deadly accident. Archie quickly discovers that instead of entering heaven's pearly gates, he is being sent back to earth to clean up the mess he's created. Since Archie has an abolute dislike for animals, especially dogs, it is quickly decided he return to earth as a dog. Not any dog, mind you, but a fluffy white Pomeranian named "Quigley". Sweeney (Oz Perkins), an "observing" guardian angel, will accompany him. He is the only person who will actually see the real Archie. Everyone else sees Quigley. He's given two very different assignments. One is to retrieve the CD-ROM before it's played and the other is to help his brother, Woodward (Christopher Atkins) and his family, whom he hasn't talked to in years. Quigley has much to do and little time to do it. How he accomplishes these assignments as a DOG makes for a hysterical adventure of madcap entertainment.
