La edad de la ira

The age of anger begins when Marcos, a 16-year-old teenager who has just started high school, murders his widowed father with a typewriter, seriously injures one of his three brothers with scissors and causes minor injuries to another. The brutality and lack of apparent motives for this crime pushes Santiago, a writer in his thirties, who attended high school at the same institute as Marcos, to carry out an investigation into the causes of the crime.
