The Miss They Missed (1938)

Professor Pierre is assigned to find a missing heiress whose fortune will go to a worthless relative if she isn't found. He uses most of his dialect ability in the search by posing as a Chinaman, an Englishman, a sailor and a Scotchman, but is unable to find her. He meets his sweetheart at a restaurant and, there, discovers she is the heiress he has been searching for. She breaks off their romance when she finds out she is rich.
