[Machine Translation] Steel body, one fist to cut through destiny. The roar of a lone warrior who threw himself into the underground martial arts. This action film is known as one of Jean-Claude Van Damme's best-known early works. The film is characterized by a fighting style that is realistic and a direction that puts physical expression at the forefront. Set in the illegal world of underground martial arts, the film depicts the loneliness and family love of a man living as an immigrant. Director Sheldon Letick's rigid and lean direction conveys the atmosphere of 90's action films. In addition to the intensity of the fight scenes, the film's high level of drama gives it weight as a whole. Leon, a member of the French Foreign Legion, receives word that his brother has been seriously wounded and, in violation of orders, travels to the United States. However, by the time he arrives, his brother is already dead, and all that is left is his young niece and her mother. With no residency permit and no money, Leon enters the world of underground martial arts in Los Angeles in order to support his family. In illegal betting matches held on the streets, in warehouses, and in the arena, Leon shows his overwhelming strength and soon becomes known as "Lionheart. However, the more victories he wins, the deeper his ties to the underworld grow, and the further away from a life of freedom he becomes. Leon is torn between his goal of protecting his brother's family and his desire to escape the dangerous world. In order to put everything into perspective, he throws himself into a final battle.
