The city of Clemens has become a dangerous place overrun by crime, as violence and drug problems escalate under the control of the Amigo Mafia led by Sanchez. At Mario's small bar in a corner of Clemens, Sanchez shows up as usual to harass him—until a sudden appearance by a sexy masked man swiftly defeats Sanchez and his henchmen. The mysterious man leaves a message with Mario, urging him to meet prosecutor Yukiko Furuse to help arrest Sanchez, then vanishes. Driven by a strong sense of justice, Mario teams up with Yukiko to expose the Amigo Mafia's crimes, but they soon fall victim to Sanchez's retaliation—Mario's wife, Elizabeth, is kidnapped.
