Arno Kulm, an internationally successful actor, is privately rather a shy person, not least because of his psychologically unstable wife Inge, who cannot endure his success. Kulm regularly seeks the support and advice of his friend Dr. Winter, his agent and confidant of many years` standing. Kulm trusts his friend so implicitly that he has even appointed him administrator of the huge personal fortune that Kulm`s wife has brought into the marriage. Winter, however, is involved in several shady dealings. He is only feigning friendliness, and is exploiting Kulm for his own ends. Together with his mistress Sylvie, an unscrupulous French journalist, he plans to make the ageing actor`s fortune his own. Kulm fell head over heels in love with Sylvie during a TV report, and Dr. Winter and Sylvie plan to exploit this for their own ends.
