In January 1956, a new pop phenomenon appeared in the UK charts: a British artist playing a guitar. His name was Lonnie Donegan and the song he sang was Rock Island Line. Donegan’s rough-and-ready style was at odds with the polished crooners who dominated the charts. He played the guitar in a way that sounded like anyone could do it. Rock Island Line sounded like nothing else on the radio and it inspired a generation of British youths to pick up guitars and begin a journey that would take them to the top of the American charts.

Delving into our collective nightmares, this horror-documentary investigates the origins of our most terrifying urban legends and the true stories that may have inspired them.
