Chantecoq

Paris, 1912. A German spy steals the plans for a revolutionary "combat aircraft". The inventor's daughter, Germaine Aubry, volunteers to bring them back. Disguised as a governess, Germaine infiltrates the highest levels of the German military. When she's finally unmasked and imprisoned, her father and her aviator fiancé call on the ultimate secret agent to help bring her home. But even the mercurial, theatrical Chantecoq will find his ingenuity stretched to the very limits to rescue Germaine Aubry from Spandau Citadel.

When German spies infiltrate French munitions factories for a sustained campaign of sabotage and terror, only one man can uncover their sinister plot. Posing as an engineer at the Douai powder mill, Chantecoq's investigation is quickly derailed by murder and intrigue. To uncover the enemy spy network, France's greatest bloodhound must reunite with old friends...and beware old enemies. Kaiser Wilhelm II of Germany has set a deadly plan in motion, but it's not his own plan.

The noble Lieutenant Vallier stands accused of murdering his superior, Colonel Richard, and of high treason against France. Facing a court martial and the firing squad, only four people believe him: the genius inventor Jean Aubry, his heroic daughter Germaine, the intrepid test pilot Maurice Evrard, and Yvonne Richard, daughter of the murdered hero, and the dashing lieutenant's young love.
