Two men in a room with a white wall and a shelf, one in a red shirt and the other in a black shirt and white cap, engage in a repeated sequence where the man in the red shirt holds a knife and the man in the black shirt grabs his arm, then the man in the red shirt pretends to stab the other man's arm, and the man in the black shirt reacts by pulling his arm away and then pushing the man in the red shirt back.
