Researching primitive life in the desert, two scientists find a huge and welcome cave. God sends them an urgent message inside the cave. In our brains, he created circuits of neurons to give us more than a hundred powerful instincts-far more than any animal. These instincts let hominids and stone-age men survive.

But for humans living in cities for over 5,000 years, for people today with technological weapons-the instincts can make of man a monster.

The Archangel shows what our circuits are-and warns that now they can destroy us.
