The story is set against the backdrop of the British underground porn industry, with a lively pace and no taboos. The struggle between defenders and cynics breaks into the bedroom from the courtroom. Harding, a congressman who is determined to overthrow the porn industry to reverse the moral atmosphere, sent Peter, a young man who is not involved in the world, to sneak into an underground porn group in order to collect illegal evidence and file a complaint with the court. Peter is still a virgin, deeply Christian, usually dependent on his mother, life is simple, but one foot into the transsexual activities as the routine environment, the impact can be imagined. The congressman was excited by the intelligence and evidence obtained by Peter, but on the other hand, Peter became infatuated with the head of the performance group, Tang Ya. Peter hopes that Tang Ya from New York can settle down like other women and often perform secretly in the United States and Britain.
