In order to repay a huge debt, the down-and-out young man Chen Mo took on a high-risk job - staying in the century-old haunted Oak Manor as a "haunted house sleep tester". If you survive for seven days, you can get a sky-high commission. The employer left behind seven strange rules:
Rule 1: No matter what you hear, never leave the bedroom.
Rule 2: When footsteps sound at midnight, you must pretend to be asleep.
Rule 3: Turn on the lights immediately if you smell rancid odor.
Rule 4: Mirrors are safe and the people in the mirror will not hurt you.
Rule 5: If a stranger appears in the mirror, smile immediately.
Rule 6: Absolutely no entry into the basement.
Rule 7: Don't believe in any rules.
