A radical testimony of the strongest known natural psychedelic, tryptamine 5-MeO-DMT produced by Bufo Alvarius, a toad of the Sonoran desert. The breathtaking audio-visual adventure is enhanced by immersive animations inspired by the psychoactive effects of this extraordinary substance. Fascinating stories of a group of Czech psychonauts are combined with personal insights of Stanislav Grof, a nestor of transpersonal psychology, and Octavio Rettig, a modern shaman who has facilitated ceremonial contact with Bufo Alvarius for thousands of volunteers from around the world. For many, the experience has been life-changing. Originally intended to simply document these experiences, the film evolved into an intense meditation on the nature of consciousness and being. 索诺兰沙漠蟾蜍阿尔瓦利乌斯（Bufo Alvarius）产生的色胺5-MeO-DMT，是已知最强的天然迷幻药。惊心动魄的视听冒险是由这个非凡的物质的精神效果启发沉浸式动画增强。一群捷克精神病学家的引人入胜的故事结合了斯坦尼斯拉夫·格罗夫（Stanislav Grof）和奥克塔维奥·雷蒂格（Octavio Rettig）的个人见解，后者是一位现代萨满，曾为来自世界各地的数千名志愿者与大蟾蜍·阿尔瓦利乌斯（Bufo Alvarius）进行仪式性接触。对许多人来说，这种经历改变了他们的生活。这部电影最初只是为了记录这些经历，后来演变成对意识和存在本质的强烈沉思。
