Lin Wan was an expelled intermediary in the underworld. He was accidentally bound to the "underworld real estate system" and was forced to become the only licensed intermediary in the underworld. Her clients are ghosts stranded in the human world: a starving ghost who wants a "24-hour hot pot room", a showman who wants to make a supernatural short video, and even civil servants from the underworld are coming to grab "low-rent housing". There are bizarre stories hidden in each apartment. During the transaction, you have to deal with the doubts of the landlord in the earthly world, the reports from the security guards of the community, and the weird requests of the ghosts. While signing the contract with the "yin and yang contract", she relied on "obsession to satisfy the service" to resolve the crisis. In the gap between the world of the world and the underworld, she became the "gold medal agent" who best understands ghosts.
