Ricardo Meneses

Sergio is a brooding, alienated man who works as a trash collector in Lisbon by day and roams the city streets by night seeking rough, anonymous sex with men. One night he meets a man who seems to be the embodiment of his tormented fantasies, and he becomes obsessed with the stranger until loneliness and unfulfilled desire propel him finally into a dark and dangerous animalistic state.

João Pedro Rodrigues answers the question from the title with an autobiographical short-film.
