Seok-hwan works as a debt collector while his older brother Dong-hwan struggles as a maths professor.

While investigating, Tae-su is attacked by youth gangs, where he barely escapes with his life after Seok-hwan's unexpected arrival.

After hunting the gangs, they discover Wang-jae's death was not a random mindless attack, but a planned murder.

Later, Pil-ho badly thrashes Tae-su and also targets to finish Seok-hwan, Dong-hwan and their mother in an accident, but Seok-wan survives.

Tae-su and Seok-hwan storm Pil-ho's fortress, where they fight their way through swarms of armed cooks until the banquet room.
