About the meeting of the world's first female promoter and a hard-working boxer, and every moment they cry, grumble, and cheer each other on until the day they become world champions, brimming with humanity. Sim Yeong Ja is the world's first female promoter. She transforms from Ko Su Mi, a popular actress who dominated the 1970s, into Sim Yeong Ja, the world’s first female boxing promoter. Known in her high school days as “Sim Dark,” she is a character with powerful charisma and a strong sense of justice who, through her forward-thinking strategies, shook up the boxing scene of the 1980s, a time when women were often excluded.
