Part wolf and fiercely independent, Jim Ugly is a dog who answers to only one person. Unfortunately, that man -- Sam Bannock -- has disappeared. Rumor has it that Sam is dead, but to his son, Jake, something about that doesn't sound quite right. So Jake and Jim Ugly embark on a wild journey into the frontier West, where they find themselves pursued by a pretty lady, a theater troupe, and one very ornery yellow-legged man. And they all want to know one thing: Where is Sam Bannock?
