The story, without the spoilers.
In Tokyo, police find a mutilated body beside a message written in Korean. Soon after, a similar body is found in Seoul, this time with a message written in Japanese. The pattern is too exact to be a coincidence, and too strange for either police force to solve alone. Seoul detective Kim Seok, a cool-headed investigator from the Metropolitan Police Agency's Mobile Investigation Unit, is paired with Inose, a passionate detective from the Tokyo Metropolitan Police Department's First Investigation Division. They work in different languages, under different rules, and with very different instincts about how a case should be run. As the murders continue, their search pulls them toward Lee Yun-ok, a powerful Korean-Japanese businesswoman whose connections reach into places the police cannot easily follow. Based on the 2002 Korean-Japanese manhwa Blue Road and set in 2002, the year Korea and Japan jointly hosted the World Cup, this eight-episode Netflix crime drama follows two detectives across a border a killer is already crossing with ease.
A little curiosity. A new favourite.
