After going through a real estate fraud group, he becomes a “political gangster” and lives his life to avenge his father’s unjust death.

But when Gang-jo steals from Sang-tae, a happily married but mundane family man, and embarrasses him in front of his family, he is about to find out that the toughest opponents come in the strangest packages.
