Stepping into dormitory 404 of the university, Lin Yu, Chen Yang, Zhao Xuan and Zhou Yi thought they were starting an ordinary campus life. Unexpectedly, the strange rules written in blood on the wall became the beginning of their nightmare.
First, Chen Yang was enveloped in an inexplicable chill after looking in the mirror. Then, items moved for no apparent reason, the phone automatically played scary sound effects, books opened by themselves late at night, and the quilt was lifted in the middle of the night. They began to strictly follow the rules and at the same time investigated the history of the dormitory. They discovered a bizarre murder many years ago and suspected that the ghost of the deceased was responsible.
After the soul-calling ceremony, the crisis suddenly escalated. The whispers became clearer. Some people saw the figure of the deceased in their dreams. Zhou Yi was dragged away for opening the door illegally. Lin Yu and others took an adventure to explore and unearthed the truth behind the murder case. It turned out that an evil formation trapped the wronged soul.
A fierce showdown with wronged souls is about to begin. Can they rely on their mastery of the rules and firm belief to destroy the formation, solve the mystery, and escape from this cursed dormitory 404?
