Ozzy is a friendly and lovable beagle. When his owners, the Martins, decide to go on vacation, they find out there are no dogs allowed. Wanting the best for their beloved companion, they discover a high-end canine spa called Blue Creek and book Ozzy in for the length of their vacation.
When Ozzy checks in and the Martins leave, he finds to his dismay that the spa is far from the cozy, loving place that was advertised. Instead, it's a facade constructed by its villainous owner to capture dogs. Ozzy winds up in the real Blue Creek, a prison for dogs. Along with his new friends, Chester, Fronky and Doc, Ozzy has to come up with a way to escape.
