Animal Cruelty Investigator Mark Smith seizes upon a new Phoenix city ordinance that makes it illegal to keep a dog on a chain when temperatures climb over 100 degrees. Tempers fray as he is confronted by aggressive dogs and angry home-owners as he educates them about the new law. For the city’s animals Phoenix traffic poses a constant danger. Cynthia and Juju both bring in animals who have suffered traumatic injuries from car accidents and its up to the busy team at the Second Chance Animal Trauma Hospital to set them on the path to recovery.
