THE PRUMONT METHOD is a darkly funny story capturing the wild last gasp of a family in retrograde against the backdrop of gun violence run amok in America. Staring down the barrel of a crumbling career and imploding marriage, "math hobbyist" Roger Prumont, unwittingly creates a formula that might predict when and where the next mass shooting occurs. He hits the road (where he's joined by his unimpressed daughter) to test whether the Method could actually save lives, except he might just be risking his own in the process.
