Following his breakout roles in Typhoon Family and King the Land, Lee Jun-ho returns to Netflix in the unconventional action series Cashero. The series follows Kang Sang-ung, an ordinary public servant who inherits a unique superpower: his strength is fueled entirely by the cash he carries. However, this power comes with a literal price—the money vanishes with every use.
Alongside his pragmatic, math-whiz girlfriend Kim Min-suk (Kim Hye-jun), Sang-ung initially vows to keep his powers dormant to save for their future. But his compassion leads him into a conflict with Beominhoe, a shadowy organization led by the ruthless Jo family—siblings Jo Anna (Kang Hanna) and Jo Nathan (Lee Chae-min)—who hunt superhumans to steal their abilities.
Lee Jun-ho stars as Kang Sang-ung, whose powers are tied to his bank balance.
The Final Showdown: Sang-ung vs. Jo Nathan
The conflict reaches a boiling point when Jo Nathan—fueled by drugs that replicate superpowers—kidnaps Min-suk and attacks an apartment complex. Sang-ung finds himself outmatched by Beominhoe’s unlimited resources, nearly reaching his breaking point.
The tide turns when the ordinary residents of the apartment complex realize Sang-ung needs cash to fight. In a powerful display of collective effort, they begin hurling their own money toward him. This community support, combined with the aid of fellow superhumans like the phase-shifting lawyer Byeon Ho-in (Kim Byong-chul) and the calorie-powered telekinetic Bang Eun-mi (Kim Hyang-gi), allows Sang-ung to deliver the final blow to Nathan.
Fellow superhumans Eun-mi, Ho-in, and Sang-ung join forces against Beominhoe.
Karmic Justice and a New Beginning
The finale delivers “perfect karmic justice” for the villains. Jo Anna meets a sudden end when a bullet she intended for her brother ricochets and kills her instead, while their father, Jo Won-do, is punished for his illegal slush funds.
For Sang-ung and Min-suk, the ending provides the quiet life they long desired. After the battle, they settle into a new home and prepare for the arrival of their first child. While some heroes face lingering costs—such as Ho-in struggling with passing his harmful abilities to his daughter—the core message remains one of protection and sacrifice. As Kim Hye-jun puts it, “There may be some sacrifices involved, but even so, there are things we must protect.”
Cashero explores the true meaning of strength and community.
