Duel (Season 1)

Duel (2017) is a Korean crime thriller you can watch online on iFILM. Chief detective Jang Deuk-Cheon runs one of Seoul's toughest crime units — calm under pressure at work, a devoted father at home. The morning his daughter is kidnapped, the entire investigation flips: the prime suspect looks exactly like him.

Director Lee Jong-jae built the show around a human-cloning conspiracy where the clone has no memory of its past and the original has every reason for revenge. Which one survives, and which one deserves to? Duel moves slowly and deliberately, keeping its central ambiguity intact right up to the finale. Stream all episodes of Duel (2017) on iFILM.
