Lee Sang Hoon has always wanted to prove himself to his boss, Na Yoo Seong, as a way of thanking him for having taken him in after being thrown out on the streets. Moon Ji Yong feels like he owes his life to his boss and is willing to do anything, as a token of appreciation. Na Yoo Seong on the other side notices this and uses it to his advantage, and appoints Lee Sang Hoon the new head of the drug syndicate, thus making him a wanted criminal by the Narcotics Department at Seoul police station.
