Physics lecturer David Swift is summoned to hospital to comfort his dying mentor, a renowned scientist suffering from horrifying wounds. David is shocked when the old man dies after wheezing 'Einheitlichen Feldtheorie': The Destroyer of Worlds. The Theory of Everything. It was Einstein's lifetime quest to pin down a unified set of equations, combining physics of stars with the laws of atoms. He died without achieving this goal. Or did he? In the two hours after hearing these words, David's ex-wife and child are threatened; he's attacked by a Russian assassin, arrested by the FBI and nearly killed three times. But he's too busy running for his life to work out what it all means. Teaming up with his ex-girlfriend and an autistic teenager addicted to video games, David must work out what Einstein's theories could possibly be worth to the powers desperate for them - and if the world is ready for the consquences.
