The so-called "Righteous Bully" trio decides to go to Seoul with their mother's secret money. They arrived in Seoul, filled with dreams of a bumpkin, but on the verge of losing their money in front of their eyes.

The dumb-heads jumped into a fight in the gambling den instead of the streets. The moment the betting begins, there is no turning back!
