Stanley is dog-tired of his yard, and he longs for the big wild world beyond the fence. so when he discovers a way out... he's gone! A few days later, five dogs are on the lam. And with Stanley in the lead, they're off to have the kind of fun you can't find in a yard -- chasing tomcats, sampling tasty garbage, and soaking fire hydrants. Then, late at night, atop the steepest hill in town, they come across a mysterious wheeled... thing. And before you can say "Hot dog!", Stanley's off on the ride of a lifetime!
