Dumbheaded Duo (2020)

Jung-man, seeking an escape from his routine, starts a part-time job as a "human sandbag." He teams up with Hwi, a tough guy, and Mingyu, the strongest, as they travel together using only a single glove. Despite their success in escaping, neither money nor adrenaline provides lasting satisfaction, and their desire for a fight intensifies. A mysterious former classmate, Yoo-young, appears with an offer to triple their earnings, leading them to secretly run an underground gambling den. The trio finds themselves fighting inside the den instead of on the streets, and once the betting begins, there's no going back.
