Tian Sheng peeps into the Chen family's flat and sees cups floating in mid-air. He reckons that the Chens' flat is haunted. He tells his family and neighbours, causing fear to spread quickly amongst them. To salvage the situation, the alien leader Feng Jiao uses a device to enter Tian Sheng's dreamland, inserting new information into his brain. She then puts up an act with the rest of the aliens and this finally dispels the suspicions Tian Sheng has.
