Hands exchange banknotes for plastic. Spiel is a 3D documentary about the business of gambling. In atmospheric images, it observes the operation of the Baden-Baden casino. Something very interesting happens in Bastian Epple's film: the documentary images that accompany the operation of a casino increasingly slip into an atmospheric story of people, machines and movements. The film oscillates between reality and fiction, the movements of this pendulum become ever larger and ultimately blurred.
