The Witness

An ordinary man witnesses a cruel murder and becomes entangled in circumstances out of his control. Lee Sung-min stars as Sang-hoon, who hears a woman's scream from his apartment and sees the killer Tae-ho (Kwak Si-yang) hit her with a hammer. Despite being terrified, Sang-hoon doesn't call the police for fear of retaliation, leading to the murder victim's gruesome discovery the next day. As more residents come forward as witnesses, Sang-hoon tries to protect himself and his family from the murderer, but eventually breaks down and confesses, leading to Tae-ho's eventual arrest.
