In this slick South Korean remake of 2012’s dark and gritty Chinese film Drug War, a seriously determined cop obsessed with bringing down the leader of Asia’s largest drug cartel works with a small-time gang member intent on seeking revenge. As the tagline says, sometimes you must “Trust in a sinner to catch a devil.” Sounds like a plan. Co-written and directed by Lee Hae-young and starring Kim Joo-hyuk in his final film role.
