I can know many things though I can’t see.I saw it clearly with these eyes! One rainy night, a young, blind woman named Soo-ah gets on a taxi. As Soo-ah starts to think the taxi driver is overly nice, the car bumps into something big. Soo-ah senses the driver dragging and loading something onto the trunk. He says it’s a dog, but she knows he’s lying. Later, she reports this to the police, but they ignore her. The next day, the police visit her about a missing college girl. Despite concerns, Soo-ah testifies information that is more reliable than any account from an eye witness for she had been attending police academy when she lost her sight. Later, another eye witness, a teenage runaway named Gi-sub, steps in. He starts filling in the missing pieces. Forming an odd friendship, the two witnesses help the police in finding the suspect until the culprit realizes they are close on his trail. The serial killer is now on a hunt to get rid of the witnesses. When the killer finds Soo-ah, she calls Gi-sub. With Gi-sub’s help over the videophone, Soo-ah escapes. Later, the killer tracks her down and Soo-ah realizes that in order to save Gi-sub she has to risk her own life and face the killer with only her acute senses to rely on.
