Attempt of a scene for "Who owns what?"

On a sunny afternoon a young man is walking on a small street, in the middle of two tall flat buildings. The man is wearing a suite and has a leather bag hanging on his shoulder.  He stops for a second, looks around and takes something out of his pocket. He's holding a joint. He lights it and breaths in the smoke with a calm expression. All of a sudden our running character comes out from behind the corner and crushes into him, scaring the young man and making him drop his joint. He starts to swear with anger and follows the runner as he goes away. Then he looks down and bows for picking up his spliff. But on the ground he sees some small marijuana bags arranged like a path that leads to a slightly open black metal door in the building on his right. The man walks the “path” putting all the bags in his pocket and finds himself in front of the door. He opens it and sees other bags on the floor of a long corridor. He hesitates but shortly after he enters. While he greedily continues to fill up his pockets hears some music coming out from the long aisle and in the same time he also hears shouts coming from outside, at his back. He turns around and from behind the door sees what is happening on the alley. Two men are beating up another man who, overwhelmed by the hits is falling on the ground. The young man inside feels like acting to save the guy in trouble. He slightly opens the door and takes half step for coming out but in the same moment turns his look on the corridor floor and sees again the inviting bags. He pulls back the door unable to decide and after a few seconds looks outside again. One of the two aggressors continues to hit the mourning man and while he’s putting a gun against his head he is shouting: “My fucking stuff, my fucking money, my fucking neighborhood!". The man inside observes terrified. The two leave the man on the ground and start walking towards the black door . Behind it the man in the suit is looking through the long corridor for a place to hide and the fear is growing on his face. As soon as the two are about to open the door the person behind it pulls it towards him and shuts it, leaving the screen black. Cut to our main character running…

If  we decide not to use dialog we can transform words in sounds that will imply the idea, here's a nice example:
