Eenmaal geslagen, nooit meer bewogen

Just your ordinary video store around the corner: A woman enters, grabs a videotape and goes to the counter. She pulls a gun and asks for money. "Quick, quick, quick!" The cashier looks anxious and hands over the money. But just when she turns around to walk away, the cashier pulls a shotgun and fires. Is it for real? Apparently not, because someone shouts: Stop! and we suddenly find ourselves on a film set. The director seems to disagree however with the decision to stop shooting. She reflects on the situation. Then, just few moments later, the director is lying in bed. Was the film set real? Was it fiction?
