The pampered life of Ozzy, a loveable beagle, is turned upside down when his family leaves him in what seems to be the best canine spa, Blue Creek, before going on a long vacation. But the place's perfect appearance turns out to be a fac̨ade concocted by its villainous owner, Mr. Robbins. Ozzy soon discovers that Blue Creek is a jail for dogs, inhabited mainly by tough street mongrels and where it's a case of survival of the fittest.
