In the 1970s in Argentina a wealthy family seems to live an ideal existence until the morning after a farewell party held in honor of the son, the father, Fermín López, appears dead on his desk. Everything indicates that he was murdered. The public is surprised but not the employees of his factory or the domestic staff or his own family as anyone around him could have wished his death, but who did it? Laura, the wife, confesses as being guilty, perhaps to cover up for her children, who defend her even at the risk of incriminating themselves. The young criminal investigator Colombo is determined to clarify the homicide, but she will have to fight against a patriarchal system that defends abuses and tries to subject her to the mandates of a society that protects the perpetrators and condemns the victims. Her effort to discover the truth will go beyond the case, as she will uncover injustices and abuses within and outside the family environment.
