The Silence of Men (1969)

Twelve-year old Standa (Erik Pardus) is bored. He would like to go out but it is pouring outside. When he wants to borrow an umbrella from his neighbor, the old postman Skvor, he finds him hanging dead. At that instant, the open mouth of the shocked boy is covered by the hand of a man hidden behind the door. The young man (Svatopluk Matyás) begs Standa for silence, explaining that he has nothing to do with the death of the old man but does not want to get involved in the case.
