Cesar is asked to help a dog named Yoshi, who is so aggressive towards other dogs, that his owners have kept him locked up for a year. To make matters worse, the owners have an infant daughter and are scared that once she learns to crawl, Yoshi will try to bite her. When the dog is brought outdoors for the first time in a year, he attacks a poodle. Cesar uses the incipient as a teachable moment and the foundation of his rehabilitation strategy. Can Cesar help Yoshi to function outside his apartment?
