After Kenneth Barton absconds with stolen funds, the bankers' association finds a love letter in his effects that suggests he may have run away to Hungary. The association sends detective Steve Macy to Budapest to find the woman who wrote the letter and capture Barton. In Budapest, Steve pretends to be Barton and allows himself to be arrested because he hopes that newspaper reports of the arrest will attract Barton's lover. Dr. Valerie Wilson, an American studying in Budapest who believes that Barton had helped her father in the past, comes to the jail to offer her help. She immediately realizes that Steve is not Barton, and he is released from jail. He and Valerie have dinner, but she leaves early to see a patient. Because he is sure the patient is really Barton, Steve follows her. In fact, much to Valerie's surprise, Barton is waiting for her in her apartment. Barton convinces Valerie that he has been falsely accused, and she agrees to help him elude Steve. Lola Carroll, Barton's former girlfriend, arrives in Budapest determined to get her share of the stolen money. She is befriended by Sandor, an impoverished count, who thinks she is a wealthy American woman. Meanwhile, Valerie has given Barton the keys to a country house belonging to her friend, Dr. Paul Azarny, where he can hide. Paul convinces Valerie that Barton will be safe only after he crosses the border, so she picks up Barton's suitcases and takes the train to the country to help him escape. She is followed by Steve, Sandor, Lola and a reporter, Smitty. Even after Steve tells Valerie about Barton's crimes, she still believes in his innocence, but when Steve tells Valerie that he will help clear Barton's name if he is not really guilty of the crime, she agrees to ask Barton to turn himself in to Steve. At first, Barton pretends to go along with Valerie's suggestion, but later attempts an escape with Lola. Steve captures them and Smitty covers the story. After everything is cleared up, Valerie and Steve embrace.
