After two years of living in Korea, the Covid pandemic led Cherry to return to Hong Kong. Creating a YouTube channel will make her want to increase the number of followers. When weird things start happening all around her, she blames it on the existence of virtual ghosts and asks for help to try to exorcise them.

Mr. K.K. Ho (starring Vincent WONG), is a leading “star tutor” with remarkable achievements. Lee Lung Kei (starring Hugo NG), the stingy boss and principal of the cram school, regards Mr. Ho as a trump card. Chloe (starring Jennifer YU Heung Ying), a traditional high school teacher, has always tried her best in teaching. Chloe despises K.K.’s teaching methods and refers to them as deviant. The two of them give tit for tat in class. Their conflict leads to K.K.’s appreciation for Chloe. He gives her flowers as an apology, but Chloe never accepts. He finds out Chloe is the daughter of Principal Lee. When she was young, she witnessed her mother being bullied and died by accident.

Heung Wing has been sensitive to paranormal activity and keeps seeing ghosts since he was a kid. One day, Heung Wing receives news that his mother is in coma after committing suicide, which forces him to return to the old home. Everything seems strange and weird.
