A stripped-down account of a young man's existential reckoning. "As dust hides a mirror, lust hides the self," reads one of the film's Vedanta-sourced intertitles. And indeed, while the Pierre Clementi protagonist's inner life remains obscure, the Saint-Germain-des-Pres neighborhood that offers his temptations appears in harrowing detail.
