One hundred thousand people disappear mysteriously around the world every year, and only a few people come back alive - they all have one thing in common: they follow a set of incredible "rules" in a strange closed space.
Lin Yue thought he had just rented a cheap house, until the day he signed the contract, the landlord sent a copy of the "Galaxy Apartment Tenant Rules":
"Please do not take the elevator after 11:30 at night."
"If elevator button '18' turns red, please do not press it."
"If you reach the 18th floor, no matter what you see, don't step out of the elevator door."

"The elevator has arrived. Please leave with your back to the elevator door."
