Hamburg, Germany: 2012. A mysterious, tortured and near-dead half-Chechen, half-Russian man arrives in the city's Islamic community desperate for help and looking to recover his late Russian father's ill-gotten fortune. Nothing about this man seems to add up; is he a victim or a thief or, worse still, an extremist intent on destruction? Drawn into this web of intrigue are a banker and a young lawyer who is determined to defend the defenseless. All the while, they are being watched by the chief of a covert German spy unit, who fights to put the pieces together as the clock ticks.
