Ozzy, a friendly, peaceful beagle has his idyllic life turned upside down when the Martins leave on a long and distant trip. There's only one problem: no dogs allowed! Unable to bring their beloved Ozzy along for the ride, they settle on the next best thing, a top-of-the-line canine spa called Bluecreek. This picture perfect place turns out to be a façade constructed by its villainous owner to capture dogs. Ozzy will soon end up in the real Bluecreek, a prison for dogs, run by dogs. This prison is inhabited mostly by stray mutts, where only the toughest of dogs survive. Ozzy will have to avoid danger and find strength in his new friends, Chester, Fronky, and Doc to escape the prison and return safely home.
