We visit the girls in their rural American home and then follow them as they travel to London, via an alarming trip to the Ukraine. They cast out spirits and sell DVDs – including the tempting-sounding ‘Twenty Most Dynamic Exorcisms’. They may look like a trio of sorority girls but they operate a zero-tolerance policy towards everything from pagan carvings in churches to spiritualist groups.
The film culminates with an explosive, public casting out of demons in Stratford which does little to dispel the suspicion that subjects are simply reacting to a created atmosphere – but then most people knew that anyway, right? A variously funny, sad and infuriating insight into the power of despair and belief, which will leave you gasping incredulously in places.
