But with the passage of the Nuremberg Laws, it is decreed that Jews are forbidden to have pets. After weeks on the street, Kaleb is swept up and brought to a Nazi training camp. There he's taught how to hunt, track, and attack Jews. Kaleb becomes the dog of an SS Officer in a work camp. One day, a train arrives at the camp. Kaleb is there to attack anyone who tries to escape, but a familiar scent distracts him. Suddenly, he sees Joshua, his beloved master and friend.
