Kang Sang-ung (Lee Jun-ho) is just a down-to-earth civil worker who dreams of owning a home — until he suddenly gains superpowers that are directly intertwined with the amount of cash he has in his pocket. Every time he throws a punch, his bank balance drops, forcing him and his longtime girlfriend Kim Min-suk (Kim Hye-jun) — a razor-sharp math whiz — to crunch the numbers on the heroics that burn through his pay.

Sang-ung soon learns he’s not the only one with powers when he’s approached by lawyer Byeon Ho-in (Kim Byong-chul), the head of the Korean Coalition of Superheroes, whose own abilities kick in when he drinks. Ho-in sees Sang-ung as a potential ally in his fight against the mysterious “Criminal Association,” which hunts down superheroes. They team up with Bang Eun-mi (Kim Hyang-gi), a pastry-loving telekinetic whose powers are linked to her caloric intake, to take on the evil forces of the Criminal Association and defend everyday peace.
