Bruno Reidal, a young farmer and seminarian from a small village in the French Cantal region, is taken into custody in 1905 for having killed a young boy. He writes his confession - a tale of a tourmented life - and addresses it to the medical doctors who have come to ascertain his madness. From the young man's voice an image takes shape - that of his own thoughts, of his own confession, of what he tries to resist. The text is magnificent, unique, and unrelenting, and so is the tone of voice that reads it. The film is centered around this omnipresent and repetitive voice, which aligns perfectly with the sequences. Vincent Le Port brings out the beauty of a true story in this remarkable, yet diabolically honest and cunning film.
