An innocent crime... incest. The biological father secretly installs a hidden camera in the family bathroom for filming. His intention is not only to record his daughter's bath time activities, but also to document her physical development through incestuous acts. The daughter, terrified by her father's disturbing transformation, is repeatedly subjected to lewd acts by these pedophilic perverts who exploit the guise of "sex education." Multi-angle filming takes place in a private home bathroom, kept absolutely secret from the mother.
