Xu Dong discovers that his phone no longer uses up battery power. It seems to be connected to a dream he had: an ordinary complaint before bed somehow granted him a wish that appears to have no real use. As he investigates whether something is wrong with his phone or with himself, Xu Dong encounters more and more strange things: strangers ignore him, the date doesn't seem to change after sunset, and he can't get in touch with his friends or family.
As time passes, Xu Dong realizes he is trapped in a strange space where everyone is like a walking corpse. These mysteries torment him until he contacts the only person who responds normally through a phone messaging app. Then he sets off to find a companion.
