故事设定在1990年，聚焦一群舞者共同参加为期3天的排演，后却变为通往毒品的地狱之旅，麻木使得有些人感觉置身天堂，但大多数人却陷入地狱。In the mid 1990's, 20 French urban dancers join together for a three-day rehearsal in a closed-down boarding school located at the heart of a forest to share one last dance. They then make one last party around a large sangria bowl. Quickly, the atmosphere becomes charged and a strange madness will seize them the whole night. If it seems obvious to them that they have been drugged, they neither know by who nor why. And it's soon impossible for them to resist to their neuroses and psychoses, numbed by the hypnotic and the increasing electric rhythm of the music. While some feel in paradise, most of them plunge into hell.
