A foreigner comes to stay with a happy family. The mother and daughter think that this gentle man with brown eyes and white skin is "a fine young man with the same kindness as Japanese people." However, this is not the case. "A pervert controlled by his sexual desires and his interest in voyeurism." That is the true nature of this man. The man secretly sets up a camera in the home. He secretly records the mother's frustrated masturbation and sexual acts on camera, and takes advantage of his position as a foreigner to have a physical relationship with the mother and daughter.
