Sonzai Zone is a speculative fiction film on intimacy and loneliness after the normalization of ambient communication media. An unlikely encounter between Yún and Souvd takes place in a near-future where social interactions are largely based on the mediation of human presence, known as ‘Sonzai-kan’. Shifting between XR games, Immersion Arcades and spatial home displays, their insidiously orchestrated relationship escalates into extreme idealization. Meanwhile, Souvd’s ex-girlfriend Ntzumi launches into undercover investigation.
