Doubt (Season 1)

Doubt (2024) is a South Korean crime thriller you can watch online on iFILM. A veteran criminal profiler has spent his career reading killers — until a case starts pointing back toward his own family.

The deeper he digs into a murder, the harder it gets to ignore that his grown daughter is tangled up in it. A man who built his life on catching other people's killers suddenly questions everything: his work, his idea of justice, whether he ever really knew his own child. Han Suk-kyu leads the cast, with Chae Won-bin and Han Ye-ri alongside him, under director Song Yeon-hwa, adapted from the Korean source titled "이토록 친밀한 배신자".

It's a cold, tightly wound drama about how far a father will go for his child, and the thin line between love and complicity. One for viewers who like bleak Korean detective stories with a moral knot at the center. Stream Doubt online on iFILM.
