More (1969) by Barbet Schroeder
aka: Mehr, immer mehr

The temptation is too strong and too alluring to resist, especially when the signal is send out by a most seductive and iridescent siren called Estelle (Mimsy “Naughty” Farmer). So no surprises, that our young and green german “I-come-from-Lübeck-and-I-am-going-to-travel-and-experience-the-world” guy Stefan Brückner (Michael Grünberg) falls directly and hopelessly for it, when she sweetly insists on sharing the experience of one of her mysterious little white sachets with him.
