Texas, mid-1970s. With the help of two teenagers, serial killer Dean Corll slaughtered approximately twenty young boys. Gisèle Vienne took these real events and adapted them to theater, with just one actor and a few puppets. That theatrical piece became a cult show. Now, Vienne herself brings it to film, with a splendid Jonathan Capdevielle and a bloodcurdling mise-en-scène.
