French filmmaker Jan Kounen turns the camera on his own decade-long involvement with ayahuasca shamanism, tracing a path that starts with a personal crisis and leads him deep into the Peruvian Amazon. He sits with indigenous shamans during ceremonies, describes the visions the brew induces, and brings in scientists, anthropologists, and psychiatrists to weigh in on what is actually happening in the brain and in the culture. The film does not treat the practice as a simple spiritual cure. It lingers on the risks: disorientation, exploitation by fake healers, the danger of losing one's grip on reality far from any hospital, and the ethical mess of Westerners importing a ritual they barely understand. Kounen's own footage from Amazonian villages sits alongside talking-head interviews back in France, so the film moves between jungle ceremony and clinical skepticism without settling the argument for you. It works as both a first-person account of an unusual practice and a caution about what happens when curiosity outruns preparation.
