Landlord M owns many share houses in Tokyo.He installs cameras in his properties to monitor the private lives of his tenants.He also infiltrates his relatives as new tenants and collects the fornication that unfolds in the communal life.Masturbation in bathrooms and toilets, sex between residents who have become sex friends, and lesbian play that is shy but full of pleasure.All of the disturbed sex activities that were secret only to the tenants were voyeurized and became fertilizer for the landlord's pocket.
