Freddy is a restaurant cook. In his moment of rest, he kills a fly. The little daughter of her boss is saddened to see the brutal action. From there, he falls into the trap of his own reasoning. 'It's not bad to kill a nasty fly. You kill her and that's it. In fact, who has not killed a fly?' Then Freddy walks with patience and without terror, by the most difficult thoughts, as an act of diagnosing the most humble of our violences.
