Unleashed - 2005

Danny can be used to fighting for his or her survival. In fact, his"master," Bart, thinks he as a pet and goes up to leashing him with a collar in order that they are able to make money in fight clubs, where Danny could be the most important competitor. Danny escapes and meets a blind piano recorder that uses music to spare the long-buried heart of the fighter and takes him in when Bart's crew is at a car accident.
