A vintage classic gay erotic drama masterpiece of gay-sex-with-a-story that is a must-see for serious LGBTQ film collectors!

This long-lost masterpiece of gay cinema centres on a handsome young stud who rides his motorcycle through a myriad of sexual encounters just full of good looking guys; from a soccer game's locker room to a dreamy and unsettling orgy where the film reaches its melancholic peak. The entire movie is full on male nudity and gay sex; with rimming, cum eating, bareback anal, and loads of oral sex, as we follow the hot motorcyclist through his erotic gay fantasies.

Blu-ray Released: July 14, 2020.

Written and directed by the mysterious Dietrich de Velsa (AKA Francis Savel / Frantz Salieri), this former painter was also the owner and artistic director of one of the first transvestites' cabaret of Paris, La Grande Eugène. Years later, he collaborated with Joseph Losey on Mr. Klein (1976) and Don Giovanni (1979). Equation to an Unknown is his only film and stands without a doubt as a masterpiece - easily one of the best French gay erotic films ever made.
