Hail Satan? takes you on the inside of the controversial, non-theistic religious organization known as «The Satanic Temple» (TST). This is one of several organizations in the U.S. using the label Satanism to promote freedom of religion and speech. TST protests in favour of the separation of church and state by utilizing the benefits given to «normal» religious organizations. If the local elementary school is given a Bible club, then it won’t take long before TST sets up a satanist club for children – to some parents’ great alarm. This, together with a series of other absurd public actions, make Hail Satan? a fascinating and comical experience.
