March 1992, in a small town in the suburbs of Paris. During an alcohol fuelled party, teenagers discover a body hidden in the bushes of a forest. A body that seems lifeless. Two weeks earlier. Simon, 16, has not shown up for class. Blood stains are found in a classroom.
Run-away, kidnap, suicide, murder? A few days later, Laetitia, a student from the same class goes missing. A young girl with no dark background or connection to Simon. The next day, Jean-Baptiste, a third student, also disappears. Rumors start to spread. The psychosis begins.
