The TVI Take

A detective communicates with a cold-case detective from the 1980s via walkie-talkie across time. One of the most formally inventive Korean crime dramas, the time communication premise is used with genuine intelligence.

The cold cases are based on real Korean crimes. Exceptional craft and the mystery mechanics are tightly constructed.
