Lin Feng rents a haunted house for cheap, and unexpectedly starts a ridiculous "AA cohabitation" with his ghost roommate Liu Chuang. From mutual fighting to tacit understanding, Lin Feng discovered that Liu Chuang did not die accidentally, but was murdered by his friend Long Aotian. He teamed up with Liu Chuang to collect evidence and clear his name. In the end, Liu Chuang was able to survive, and the two relied on each other in a special way, continuing to write a warm "family" story in the bustling city.
