Eric Sderqvist, a professor of computer science at the Royal Institute of Technology in Stockholm, has invented Mind Surf, a thought-control system that allows people with disabilities to browse the web. Meanwhile, Lebanese Samir Mustaf, a former MIT professor whose daughter Mona was killed by an Israeli cluster bomb five years earlier, has just finished creating a computer virus the world has ever seen, aimed at Israel's financial system. When Eric's wife, Hanna, falls into a coma - struck by an aggressive and previously unknown virus, after having tested her husband's invention - the doctors are at a loss. Eric becomes convinced that she has been infected by a powerful computer virus known as Mona, and that the only way he can save her life is by tracking down its creator.
