Gang Cheol whose name means iron in Korean was once a legendary street gangster in Busan, but he put away his fists and cleaned up his act for the sake of his mother Sooni, who has dementia. Things are going well for him; he now works as a stevedore at a loading dock and is pursuing a relationship with Sooji, a freespirited woman from Seoul vacationing in the port city. But Sooni is diagnosed with kidney failure and needs an expensive organ transplant that he cant afford. Knowing that Cheol is desperate for money, local gang leader Sanggon proposes that Cheol come work for him and his brother Hwigon. At first Cheol refuses, but when his debtridden best friend Jongsoo gives the deed to Cheols house to Sanggon as collateral for a private loan, hes left with no choice but to get dragged back into Busans criminal underworld. Cheol is ordered to kill a visiting Japanese Yakuza boss whose death will enable Sanggons ascension within the Korean branch of the mob organization.
