The People's Choice (1946)

Filmed in 16 mm, primarily intended for the school/institutional and home-rental, the plot has Abner Snell running for councilman in a small town. He accidentally becomes the "Mystery Lady" on a radio show after his deep bass voice becomes a strange, haunting falsetto following an attack of laryngitis, and earns a few extra dollars as such. He explains his sudden affluence to his sweetheart, Alice Tinkerton, by jokingly telling her he has robbed a bank, but not knowing that the Elmwood Bank has just been held up. Abner finally wins the girl and the election, after capturing the real bank robbers.
