Biochemical weapons expert Arndt Wolf remains obsessed with the idea that Saddam Hussein is hiding something, despite the fact that they have already unsuccessfully searched Iraq for weapons of mass destruction. No member of the United Nations shows interest in this issue, until a political refugee from the Iraqi government claims to have been involved in the creation of these weapons. The German Federal Intelligence Service decides to summon Wolf to assess whether the information about this man, who has been nicknamed "Curveball", could be true or not.
