El Tren de la Bruja (2003)

A man volunteers to take part in an experiment that attempts to analyse human behaviour under extreme conditions of terror. His mission is to remain seated inside a dark room for a length of time of 15 minutes. If he manages to hold on, he will receive in return a generous sum of money. Is it possible to terrify an individual who knows beforehand that everything is a farce?

Unfortunately the movie El Tren de la Bruja is not yet available on HBO Max.
