In the early 1970s, what was supposed to be a simple psychology study spiraled into something much darker. Students became guards, others became prisoners, and within days the line between roleplay and reality shattered. Hidden in the basement was a room few dared to enter — a place that seemed to swallow people whole.

This week on Tales from the Blur, we explore one of the most disturbing experiments ever conducted — and the haunting mystery that refuses to die. Your job is simple...determine if this is based on factual events or if it was completely fabricated. The answer will be revealed at the beginning of next week's episode.
