On a Greek island Dr Thaddeus Pilgrim, once a devout man of God but now devoted to the pursuit of murder, terrorism and sadism, plans his most sinister project yet, the Hallelujah Scenario. Pilgrim kidnaps Willie Garvin, Modesty Blaise's trusted lieutenant, and brainwashes Willie into believing that Modesty is dead and that he must kill her murderer - a woman who looks exactly like Modesty herself. A deadly game begins and they must fight the diabolical ingenuity of Pilgrim's plan.
