Yong-Goo heeft een mentale achterstand, maar is tevens de lieve en trotse vader van Ye-Seung. Op een dag wordt hij valselijk beschuldigd van de moord op een meisje en levenslang opgesloten. In de cel redt hij So Yang-Ho van een rivaliserende bendeleider en deze belooft hem te helpen met alles wat hij wenst.
Nee, helaas is 7-Beon-Bang-Ui Seon-Mul nog niet beschikbaar op Netflix in Nederland.
