In the middle of a forest, a notorious five-member crime organization lives together on a deserted farm. One day, following a plan that didn't go as expected, an infant whom they had kidnapped in a blackmailing scheme is left with them. 14 years later, this boy, who is now named Hwa-yi, lives as the son of his five criminal fathers: Seok-tae, the cold but charismatic leader, Ki-tae, a stammering driving expert, Jin-seong, an ideal planner, Beom-soo, a guns expert, and Dong-beom a cold martial artist. Hwa-yi has been brought up in a unique way, learning skills from his five fathers instead of going to school. Though he has adapted to this life, sometimes he longs for the ordinary life of other boys, which seems impossible for him.
The gang plans another crime, which will see Hwa-yi participate for the first time. During a fight, Hwa-yi fires a gun to kill someone. At first, his fingers tremble and the gun shakes but after one shot, he keeps pulling the trigger as though possessed. He finds a picture of a child on the man he shot and soon Hwa-yi starts to uncover a huge secret and his tragic destiny. His life is turned upside down when he learns that the man he killed was his real father. From that moment on, Hwa-yi vows revenge on his gangster fathers, using the devious skills he picked up from a life in crime.
Hwa-yi begins by killing one of five fathers. The rest of them go after him but lose him. Hwa-yi calls them all to Sungji Cement Factory. He also writes a letter to the rival gang and they show up an hour before. Both groups get into a feud. Hwa-yi positions himself at a high vantage point and snipes the men. Soon, everyone is dead except for Seok-tae and Hwa-yi. Seok-tae heads to the hospital where Hwa-yi's mother is admitted, Hwa-yi follows.

Hwa-yi reaches the hospital too late, he goes home to confront Seok-tae. The detective who's been after the notorious gang is also there. The three of them have a standoff.
