Believer

“To catch a devil, trust a sinner.”

Detective Won-ho (Cho Jin-woong) has chased a drug cartel's invisible kingpin for years, and the trail has run cold. After a traumatic event, a trafficker turns sides, and Won-ho teams up with Seo Young-rak (Ryu Jun-yeol), an undercover officer whose ambition runs dangerously hot, to bring the man down. Lee Hae-young, remaking Johnnie To's Drug War, keeps the camera moving and the pace tight.
