In 1985, many skulls of newborn children are found in the town of Aituy, Queilen commune, Chiloé. Initially it was suspected that it may be another crime of the dictatorship of Augusto Pinochet. But, according to forensic dating of the remains were buried between 50 and 60. The research is taken up years later by a group of filmmakers, from the finding, made during the restoration of the church of Aituy, a drawer with notes and drawings left by Father Bruno Kulczewski, a former priest, now deceased. The papers, together with declarations of the midwife Uldecinda Mancilla, which were not taken seriously at the time the bones were found, giving rise to this mockumentary, providing a new explanation, more macabre, mysterious, about the origin of the children's skulls.
