Prom, a strange foreign institution to us Brits. The subject of much teenage angst and many the culmination of movies good and bad. The Killer Queen follows a L.A.N.C.E. agent undercover as part of a film crew shooting a movie at an abandoned high school.

The script however, cuts a bit close to home. Based on real events, events that were part of an old L.A.N.C.E. case which was never satisfactorily closed. The murder spree by one girl of her entire graduating class back in the 60's.

Unsurprisingly, dredging up the past like this isn't going to go well for our poor film crew. But it's up to our agents to determine the what's causing this. Is it a demon, spirit, or just a person who'd been driven over the edge by this strange coming of age tradition?
