When reserved rookie boxer Kim Geon Woo squares off against loquacious southpaw Hong Woo Jin, Geon Woo narrowly prevails — but the two former marines become fast friends. As their friendship grows, so do the financial woes that plague Geon Woo’s mother. To save her quaint café from going under, she signs off on a hefty loan. But when it turns out she’s been targeted by Smile Capital — a ruthless loan shark business — Geon Woo and Woo Jin do everything in their power to make it right. Fate intervenes as the pair end up working for a generous money lender whose foster daughter is dead set on taking down the loan sharks.
