Hair dryer

A young man stands in a bathroom, watching a woman with long red hair who is using a hairdryer; the scene cuts to the woman falling down a dark staircase, then lying injured on the floor as a man in a white shirt stands over her, and finally to a close-up of hands gripping the edge of a trapdoor. The setting shifts from a tiled bathroom to a dimly lit stairwell and then to a dark, industrial-looking room.
