Hubert is a 16-year-old Québécois living in suburban Montreal with his single mother, Chantale, who divorced Hubert's father, Richard, when Hubert was much younger. Hubert barely sees his father, and this adds to the animosity between mother and son. At school Hubert claims to his teacher, Ms Cloutier, that his mother is dead. After the teacher finds out that it is a lie, she expresses this lie as "you killed your mother." This inspires Hubert to write an essay for school titled I killed my mother.
