The entire US intelligence community descends on Philly one weekend, and finds the city harbors a gritty spy mob of its own.

It’s September 2015, ISIS terror is all over the news, and Pope Francis is in Philly along with the entire alphabet soup of US national security and intelligence services to protect him. That’s where Philly district attorney Donna Modigliani smells a rat, in the form of a mysterious DC official who’s crashed the event’s security detail at the last minute. So in a trust-nobody move, Donna teams with Tristan Freeman, a local risk consultant with a knack for unraveling strange mysteries. But after seeming to uncover a plot to attack the event, Donna and Tristan discover they’re merely bait in an epic scheme to demolish the US government itself, and they aim to punch back with classic Philly ‘tude, while literally the world is watching.
