Eden and After (1970)

In the labyrinthine Eden Cafe where ads for Coca-Cola share wall space with living friezes of nude models and slogans like "Drink Blood" a group of French students play games of Russian Roulette, poisoning, and rape. The Dutchman (Pierre Zimmer) enters the scene and demonstrates a "trick" he learned in Africa in which he heals one of the students who he has asked to pick up pieces of broken glass. He gives fear powder (not cocaine because that's already on the menu as a beverage at the Eden Cafe) to Violette (Catherine Jourdan) and she imagines herself in Tunisia in a series of sadomasochistic vignettes with the Dutchman and her fellow students inhabiting various roles (characters playing multiple roles - including themselves as actors - is an element of several Robbe-Grillet films) suffering multiple deaths and Violette even encounters her own double. imdb
