Actor Kim Nam-gil and Seohyun of Girls' Generation will star in Netflix’s upcoming original series “Thief: Sound of the Sword,” the streaming platform said Monday.

Set in the 1920s when Korea was under Japanese colonial rule, the action series tells the story of Koreans who meet in Gando, today part of Northeastern China, and form a team to fight for other Koreans living in the region.

Kim will play a Korean man who once served in the Japanese military but left for Gando and became a thief. Seohyeon will play an employee of the railway bureau under the Government-General of Chosen, which ruled over colonial Korea.

Screenwriter Han Jung-hoon and director Hwang Joon-hyuk of the hit OCN crime action series “Bad Guys: City of Evil” (2017-18) will join forces again for “Thief: Sound of the Sword.”

Actors Yoo Jae-myung, Lee Hyun-wook and Lee Ho-jung will also appear on the show — Yoo as a Korean landowner in Gando who once led a guerilla resistance army, Lee Hyun-wook as an opportunistic Japanese military officer and Lee Ho-jung as a gunman who is trying to murder Kim’s character.
