Nurul Islam is a world-renowned physicist, professor at Imperial College, London, and one half of the Islam-Rosenfeld theory, the first step in a grand unification of forces and a Theory of Everything. A family man profoundly influenced by his pious father, Nurul is happily married to Sakina Begum by an arranged marriage. They have three children. But when Nurul travels to Cambridge, Massachusetts, to give a public lecture at Harvard, he falls in love with a graduate student, Hilary Chase. At the same time, Nurul Islam's outspoken, philosophical views about the nature of physics and God have earned him the ire of fundamentalist preachers in Pakistan. He makes enemies of the political and military establishments when he refuses to contribute to Pakistan's nuclear weapons project. Meanwhile, a contingent of physicists begins a smear campaign, claiming that Nurul Islams's contribution to the unification theory was plagiarized. All these events converge upon Sakina Begum who, smarting from her husband's betrayal, unwittingly commits a betrayal of her own. Everything that has worked together as though preordained since his childhood to take him to the pinnacle of scientific achievement suddenly falls apart.
