Bertha the Sewing Machine Girl (1926)

"Girlish Innocence! Deep-Dyed Villainy! Grand Heroics! Thrills-Laughter!"

Bertha Sloan loses her job as a sewing-machine girl and subsequently is employed as telephone girl with a lingerie manufacturing company. She soon falls in love with the assistant shipping clerk, Roy Davis, and is promoted to chief model for the firm, owing to the patronage of Morton, the wealthy and wicked manager. Bertha is about to take a position in Paris as designer when Morton lures her to his home.
