Many of them are shot dead by the German guards but young Ruda (Jaromír Hanzlík) manages to run away. He is taken care of by one of the Prague fighters, concierge Kytka. Kytka hides him in the flat of the house's owner where only the young maid Karla (Jana Brejchová) is left, ordering her to take care of Ruda.
