Nine Puzzles (Season 1)

Nine Puzzles (나인 퍼즐, 2025) is a South Korean crime series you can watch online on iFILM. Starring Kim Da-mi and Son Suk-ku, directed by Yoon Jong-bin.

Ten years ago, Cho Yi-na was there when her uncle was killed. Only witness — and also the prime suspect. The case was shelved when evidence ran dry. Since then, she has built a career as a profiler with an impeccable record. Then a new series of murders appears, each scene tagged with a puzzle piece. The detective assigned to work alongside her is the same man who spent a decade doubting her innocence.

Two investigations run in parallel: the active killer outside, and the decade-old file that won't stay closed. Kim Da-mi plays Yi-na as someone who learned precision as a form of self-defense — she can't afford a mistake, which makes watching her work genuinely tense.
