"Hossa! Hossa! Hossa! Hossa!" With his "Fiesta Mexicana," Rex Gildo became famous. As a German pop star, he brought songs about foreign countries and extravagant parties to the staid young Federal Republic, celebrated carefree life while feeling forced to hide his homosexuality in the repressive public of the 1950s and 1960s and to perform a non-aging heterosexual son-in-law dream – he even married his own cousin. The long-term relationship with his discoverer and manager Fred Miekley had to remain secret.

With the death of his lover, Rex Gildo's life and career spiral out of control; addicted to pills and alcohol, he now performs in shopping malls and tragically dies when he falls from the window of his Munich apartment in 1999. In the piece following his semi-documentary film Rex Gildo - The Last Dance , Rosa von Praunheim depicts the tragicomic decline of the pop star.
