Devo Mannix, a young boy, becomes frightened in a thunderstorm and uses his grandfather's Book of Magic and Incantations to make his dog, Speeler, speak and understand his language. He sneaks into the den of his grandfather, who is a world-renowned sorcerer and magician, in hopes of using his secret Book of Magic and Incantations to make his dog speak.
With the recently obtained power of speech and understanding, the dog entangles himself in a web of unfortunate incidents that are attributed to his owner. In an attempt to undo his magical spells and correct all of the unfortunate events that have occurred, Devo looks for ways to undo the problems caused by his impulsive actions.
The mayhem continues as Devo decides he would like to go fishing in the neighbor's pond. Devo seeks advice on fishing from his dog who believes he truly knows everything about fishing after watching one TV episode of Fishing with Fred Wilson.
Trying to ensure that there will be fish in the pond, the boy again uses his grandfather's Book of Magic and Incantations to cast a spell to stock the pond.
Sadly, the incantations the young boy cast were not what were intended. Undoing the spells with the help of his dog becomes a disaster.
This chain of events sets off a ripple effect that challenges Devo's imagination in solving this and other exciting magical adventures.
