U Seok is the top ace of the Insurance Fraud Special Investigation Unit (SIU), a relentless investigator known for chasing scammers worldwide and earning the title of the youngest deputy director thanks to his record-breaking arrest rate. Once a promising violent crimes detective, his life changed when his beloved younger sister was killed in a brutal insurance-fraud murder and the suspect, her boyfriend, walked free with a suspended sentence. Consumed by guilt and rage, U Seok left the police and dedicated himself to hunting insurance criminals with near-obsessive intensity, digging into cases until the truth surfaces, no matter the cost. When a woman dies after trying to report a suspected insurance-related murder, his investigation leads him to Han Seol A, the star auctioneer of Royal Auction, and the common link to three dead men who were once her lovers, pulling him into a mystery he refuses to let go.
