Don't Open The Door At Midnight

Fresh graduate Shen Qian rents a haunted house to save money, only to face ghostly knocks at midnight and learn that three girls went missing inside. Determined to cancel the lease, she is forced to pay a 100,000 yuan penalty by a shady agent, leaving her with no choice but to give up. Security guard Wang Shengquan steps in to help and reveals that the elderly woman who often threatened her lives on the opposite side of the building has already passed away. Desperate, Shen Qian trusts him, tells him her hiding spot, and is subsequently kidnapped. Just as the shady agent and Wang Shengquan are about to make a deal, inspectors arrive to rescue all the hostages and arrest the gang. It turns out Shen Qian is an undercover agent, and everything was part of a plan to lure the criminals out.
