The summer of 1944. Rome, Italy - somewhat battered, but liberated by the Allies and glad to be out of the war. Enter a powerful American intelligence agency, hot in pursuit of secret information. Also enter a stunted, insignificant, middle-aged, unemployed Italian journalist, fresh out of jail and desperate for work.
On the face of it, a grotesquely one-sided confrontation, heavily weighted in favour of the professionals. What could possibly go wrong? In the event, almost everything. And that's a fact.
