About the title
A young woman disappears without a trace, and a few days later another girl is struck and killed by a car whose driver flees the scene. The police begin investigating both cases, suspecting that the kidnapper and the hit-and-run driver are one and the same person. Almost the only lead that could help identify the culprit is the testimony of two witnesses — a young man named Ki-sop and a blind girl, Su-a, a promising student at the National Police Academy.
