Netflix has released the first full trailer for its upcoming Korean superhero drama Cashero, giving viewers a detailed look at the high-stakes, cash-powered action. The series confirms its global release date for December 26, 2025. Starring Lee Jun-ho, the show presents a uniquely relatable superhero whose strength is directly tied to his personal finances, forcing him to calculate the real cost of every heroic act.
What Is the Story of Cashero?
Cashero is based on a popular Kakao Webtoon and follows the life of Kang Sang-woong, played by Lee Jun-ho. He is an ordinary civil servant with modest dreams of homeownership whose life is turned upside down when he develops a superpower with a major catch: his physical strength is proportional to the amount of physical cash he has on him. Every punch or display of power literally costs him money, draining his savings as he tries to do good.
Sang-woong is not alone in his struggles. He is approached by Byeon Ho-in, a lawyer who leads a secret Korean organization for people with supernatural abilities. Ho-in’s own power activates only when he consumes alcohol. They are joined by Bang Eun-mi, a young woman with telekinetic abilities fueled entirely by her calorie intake. Together, this unlikely team must protect their normal lives and defend ordinary people from a mysterious group known as the “Criminal Association,” which is actively hunting superheroes. Standing by Sang-woong’s side is his longtime girlfriend, Kim Min-sook, a pragmatic and numbers-smart woman who supports him despite the glaring inefficiency of his expensive power.
