Tricheurs (1984)

Elric has a gambling addiction: from casino to casino, he plays the roulette table, consumed by a twisted mix of intense pleasure and desperation. His encounter with Suzie throws his life into turmoil, but instead of curing his pathological passion, Suzie also falls prey to the game. Prisoners of their destiny, the couple plunge into another, more dangerous world, that of professional con artists.
