Over a period of time, several women were slaughtered by serial killers, and each of them was left with a cruel mark. The common point between them was that they had communicated and dated with people in online chat rooms. It seemed that a perverted man used virtual space to commit inhumane crimes. On this day, a girl named Julia (Valerie Azlynn) met a stranger online (Kevin Sorbo), but perhaps she smelled an ominous breath in the dark. In the middle of the conversation, Julia got up and said goodbye, but she was caught by the other party before she had time to go far, and was forced to come to the man's residence. Yes, this man is the initiator of a series of serial murders. He listens to beautiful music and enjoys every killing process, as if it is a supreme art. It's just that the girl he met this time seems to be a little special. She escapes again and again, punches and kicks again and again. In this process, Julia's tyrannical nature in her heart is slowly activated by the killer. Hunter or prey? No one can figure it out...
