In episode 4, there's the most brutal, bloody and disturbing scene of violence in series. A man opens a door to the woman, as he thought, but there's a man, who punches him in the face two times. He starts bleeding. Afterwards the attacking man grabs the first man's head and beats it into the wood. The face is completely soaked with blood, we see it for three-four seconds. Then the attacking man cuts the other man's throat. In a couple of minutes we see the corpse of this man with a VERY big amount of blood on the body and on the floor.
