bank manager Weiss pulls a gun on a suspicious-looking customer and throws his bag into the street, thinking it is a bomb. The angry customer leaves, and while Weiss is distracted, Dragomiloff hides a real bomb that kills Weiss. Next, in Vienna the couple watch a military parade. A man behind them pulls a pistol, but he is trying to assassinate the Archduke watching the parade from a balcony opposite. Dragomiloff disdainfully remarks to Miss Winters that had "The Assassination Bureau" undertaken this "assignment", the Archduke would not remain alive. In Venice Bureau member Cesare Spado dies after being poisoned by his wife; with the help of her lover Angelo she tries to poison Dragomiloff and have Baron Muntzof kill Miss Winters. Dragomiloff not only survives the attempt on his life, but kills both Angelo and Muntzof and rescues Miss Winters. Eleanora Spado tries to blackmail the Assassination Bureau for money by using her knowledge of its existence; the Bureau's response is to have General Pinck kill her with his Luger pistol.

Their plan is to assassinate all the European heads of state. They attend a secret peace conference where the kings, emperors, and prime ministers of Europe are trying to avoid a possible war over the assassination of a Balkan prince who had accidentally been killed by a bomb intended for Dragomiloff. Dragomiloff and Miss Winter uncover the plot, which is to drop a large aerial bomb from a hijacked Zeppelin airship directly onto the castle in Ruthenia where the peace conference is being held. Dragomiloff steals aboard the airship and destroys the bomb, while disposing of Lord Bostwick and the remaining members of his board of directors. He exploits General Pinck's one weakness, a sword duel challenge to the death. He is hailed as a hero and later decorated by the heads of state that he has saved. It is implied that Dragomiloff may now wed Miss Winter, since
