When LAPD computer expert Peter Fowler investigates the killing of an old man in Chinatown, he finds the only witness is his dog, Cho Cho. But Fowler soon discovers Cho Cho is the only dog in the world who can speak to humans... not only that, Cho Cho is an expert in martial arts. When they join forces to track down the mastermind behind the death of Cho Cho's master, it leads these unusual partners into uncovering a dangerous conspiracy which puts both of their lives in danger.—Anonymous

Chin Li works for Hamilton Cage, who runs a track where greyhounds are raced. Cage also has big plans, as an illegal drug shows great promise for improving the quality of life of people. But apparently Chin Li stood in the way of this, as a masked assassin kills him in front of his dog Cho Cho. Of the cops investigating the case, only Peter Fowler, a computer geek who has developed COLAR (sort of like Siri), appears likely to be headed in the right direction. Chin Li has advised Cho Cho to talk only to those who seek truth, so Cho Cho opens up to Fowler. Fowler thinks it's some kind of trick, but he eventually believes Cho Cho is really talking. But he can't convince anyone else: the same thing happens to him that happened to that construction worker who found Michigan J. Frog. No matter: Fowler can pursue the case on his own. And he has help from the pretty Ashley, a cop who wants to be a detective like her father, her grandfather, her great-grandfather. Southern Beauty, one of the greyhounds, is really good. Too good. The truth eventually comes out, but this means potential danger for the heroes. The Cage children seem more ambitious than their father. Could they be the killers? Or does the father know everything? Or is someone else involved?
