In The Roundup: No Way Out, directed by Lee Sang-yong, the plot unfolds seven years after a capture in Vietnam. Detective Ma Seok-do (Ma Dong-seok) joins a new police squad, alongside his partner, Detective Ma (Kim Min-jae), to investigate a series of mysterious murders. Soon, the investigation reveals a manufacturing and distribution network for a lethal synthetic drug, run by the ruthless Joo Sung-chul (Lee Jun-hyuk). To complicate things even further, he has the help of the dangerous Japanese gangster Ricky (Aoki Munetaka) and his gang, who came from Japan to expand their drug business.
