In a future world, the 'Wonderland' service – which uses AI to replicate people who have died – has become widespread. Baili signs up for Wonderland in order to hide her impending death from her young daughter. After an accident leaves her boyfriend Tae-ju in a coma, Jung-in passes the days chatting with an AI-revived version of Tae-ju who has become an astronaut in space. In this way it is possible for people to choose a life free from longing and sadness.
