In 1981, gay audiences were stunned and delighted by a new, bold, sexy comedy from Germany, Taxi zum Klo, a film that set new standards for gay cinema. Eight years later, Frank is back, and his life is anything but under control. He is still madly in love with men; he's always short on money; and he has just been tied up and robbed by a hustler. On top of everything, his mother thinks it's high time he kissed his idle ways goodbye and started thinking about holy matrimony — otherwise he could end up being cut out of her will.

Frank finds Klara, an out-of-work actress who is willing to stage a marriage farce for his mother, but their scheme has just one snag: both Frank and Klara are in love with the same man, their neighbor Eugen. Suddenly jealousy is the order of the day, and Frank finds himself torn between competing with Klara for Eugen and still needing her to collect the inheritance. Goaded by Eugen, who maintains that with Frank being gay he will never be able to keep his wife, Frank snaps. He quickly engages a sex therapist to turn him into a heterosex­ual. His attempts to switch land him in a chaotic mess in which the neighbors, the police, and naturally his mother are all embroiled.
