The film takes place in Paris, where two cops are competing for the vacant seat of chief of police while in the middle of a search for a gang of violent thieves. The movie is directed by Olivier Marchal, a former police officer who spent 12 years with the French police before creating this story, which is taken in part from real facts that happened during the 1980s in France.

Raised as a slave, Danny is used to fighting for his survival. In fact, his "master," Bart, thinks of him as a pet and goes as far as leashing him with a collar so they can make money in fight clubs, where Danny is the main contender. When Bart's crew is in a car accident, Danny escapes and meets a blind, kindhearted piano tuner who takes him in and uses music to free the fighter's long-buried heart.
