The stage is set five years after the previous work... The possession cell phone app trilogy finally concludes! Possession apps, now illegal, are used to commit impersonation crimes by the Possession Twenty Faces, while a clumsy and perverted investigator corners his nemesis using a possession detection app in a public bath's women's section for a lewd game of deception! Mutual possession, soul infusion, multiple possessions, body swapping triangular lesbianism!
