This documentary film searches for answers to these questions: Is Europe undermined by miles and miles of tunnel systems, dating back thousands of years, as some scientists believe ? Or do these earth caves date from the Middle Ages ? Were they empty tombs for the souls of the dead, and eventually forbidden by the church ? How did this idea of a "soul" that is saved in an afterlife come about in the first place, and how was it utilized to increase the power and riches of the priests?
