ASPCA Special Investigators Mark McDonald and Annemarie Lucas are on their way to the Bronx. Two of their colleagues have called them in for help on a rather disturbing case. A neighbor has made a complaint about a dog with a badly infected foot. When officers arrive, they realize it's urgent that they get the dog to the hospital right away. The owners of the injured dog will have to answer to a charge of animal cruelty. While the dog is recovering, Annemarie and Joanne investigate a man who houses dozens of rabbits. Neighbors say he hurts them, but the officers must try to find out more.
