A respected police commissioner has a reputation as a fervent opera lover, but by night he also enjoys plunging into the transvestite scene. In addition, he harbors a longing for his very own sister. When he learns that his wife has been murdered, he tries to implicate the set-designer who has designs on his sister.
British soldiers force a recently captured IRA terrorist to cooperate with them and then assign him to go undercover with a gang of terrorists and prevent them from killing the U.S. President. But the spy isn't in long before he realizes that the first plot is but a ruse for a more sinister scheme that could result in trouble between China and Great Britain.
