Failed fitness coach Tony is the unluckiest man in the city: his girlfriend cheats on him with a client, he can’t pay the rent, and his muscle-building account has only 37 followers. One day, he rescues a bulldog with a luxury collar in the park. The next day, a lawyer comes to him— the dog’s owner is Victor, an underground boxing tycoon and hidden billionaire who just “died accidentally”. Victor left Tony his private boxing gym, underground training camp and the bulldog with a worse temper than its owner in his will. But the inheritance condition is absurd: Tony must lead the gym, coveted by gangsters, internet celebrities, creditors and professional boxers, to win an international championship within 30 days, otherwise all assets will go to Victor’s nephew Rex. Tony can’t fight professionally but has to take over to avoid huge liquidated damages. Rex, a violent man in a suit, is eager to get rid of him. Tony transforms the ragtag team with his gym operation skills, only to find Victor’s past sponsorship and a money-laundering ledger under the gym, and even more shockingly, Victor faked his death and used him as a pawn. Finally, Tony awakens, steps onto the ring himself, defeats the rigged opponent and exposes the evidence to take down Rex, keeping the gym and becoming its real owner instead of anyone’s substitute.
