Plot
There has been a serial disappearance of female college students and a hit-and-run accident. The victim of two different cases turned out to be the same person and the police search for any possible witness. The one witness they have is Su-ah (Kim Ha-neul), a visually-impaired former promising student at the national police university. She provides important evidence regarding the hit-and-run accident. As the investigation continues based on the exceptional senses possessed by Su-ah, another witness, Ki-seop (Yoo Seung-ho) shows up at the station. Different from Su-ah, he has actually witnessed the site of the accident and makes statements that completely contradict Su-ah's testimony, which leads the investigation in a totally different direction.
There is one case, two witnesses, and contradicting testimonies! Now begins a fierce battle to uncover the truth!
