1981 film by Carlo Verdone

Starting as an investigation, the film begins with the discovery of a murdered young woman. Gradually we go back in time to realize that this crime is altogether the logical continuation of a philosophy of life where neither sex nor death are taboo, and where a lust for pushing limits meets it ultimate conclusion.

When Heterosis — a mysterious virus that turns gay men straight sweeps through the Parisian gay scene, Jim, the six packed sovereign of the Gym Queens, goes from Pride royalty to social outcast. With only Lucien, a freshly-out twink with more heart than abs, still by his side, Jim must race to find a cure before the disease erases the community that once worshipped him.
