Nana's Game.

Tang Guan-guan is a single-minded and ruthless TV producer at the WTV television network. She is charged with creating a unique reality TV program like no other – for fans of horror and suspense. The show involves sending five contestants to spend 72 hours in a house where a terrible murder is supposed to have been committed. The house is notoriously spooky and located in a remote area, far away from other signs of civilisation, and some say that it is haunted by terrifying ghosts. At stake is a large cash prize, and the producer and her long-suffering crew decide to select their contestants from the world of social media and popular entertainment.
