Mans quietes! (2010)

A couple about to separate go to talk about their 12-year-old son to the headmistress of his school, who receives them outside school hours at a classroom at the centre. The school is empty. Halfway through the interview another mother appears and, enraged, accuses the man of having punched her son at a school party. The accusation sets off a chain of events and the father, in order to be forgiven, ends up accepting a humiliating punishment from the three women.
