David France‘s forthcoming documentary How to Survive a Plague has a title that promises important information for anyone living in the Middle Ages, but its message is entirely modern. It’s that last word, hanging like an antique from too many centuries ago.

It’s hard to think of a plague still hanging around, but that’s exactly what AIDS is. It was a misunderstood disease that saw some lawmakers fighting back against finding a cure with any relative speed, but this doc chronicles a group of men and women literally fighting for their lives.

The doc is in theaters in September.
