In the middle of the 21st century, a team of scientists develops the ultimate protective weapon — a device that causes all nitrate-based bombs and explosives nearby to detonate automatically. It seems like a benevolent invention — one that will protect mankind against weapons of mass destruction. But as the scientists struggle to ensure their invention is used only for peaceful purposes, it becomes increasingly clear that even protective weaponry comes with its own moral trade-offs.

Dr. Jeffrey Horton, the device's lead inventor, must fight to keep the weapon out of violent hands — and soon finds that not even those with the best intentions can be trusted.
