Moon-jae
Sang-gu, un famoso luchador callejero adolescente, se cansa de pelear cuando se da cuenta de que ya no hay rival para él. Sin embargo, un día, su mejor amigo Moon-je es golpeado por Min-gook, el campeón del torneo de artes marciales mixtas de su escuela. Indignado por lo sucedido, decide transferirse a la escuela de Min-gook para vengarse y participa en el torneo. A medida que vence a otros oponentes uno por uno, se acerca al pez gordo de la escuela, Min-gook.
'Jung-man', tired of his daily life, comes up with an idea of 'human sandbag' as part-time to make money. From that day on, the tough guy, 'Hwi', and the strongest guy 'Mingyu' teamed up on the road with only one glove in hand. However, escape is quick, neither money nor instinct make them satisfied, and the blood-boiling fighters' thirst is only getting deeper. One day, a mysterious alumni, 'Yoo-young' appeared and made an extraordinary offer to triple their profits, and they secretly got themselves in running a gambling den. The dumb-heads jumped into a fight in the gambling den instead of the streets. The moment the betting begins, there is no turning back!
