After winning an underground fight, a dangerous fighter named Axel is approached by a well-dressed man's assistant who offers to buy his service. Axel scoffs at the offer, demanding the boss come himself. The man appears, dressed in black, and proposes to buy Axel as his bodyguard or 'obedient dog.' Insulted and calling him a 'spoiled rich boy,' Axel challenges the man to enter the fighting ring, stating that if the man can beat him, Axel will serve him; if Axel wins, the man must leave. The man accepts, overriding his security's protests, and steps into the ring to face the volatile fighter.
