My Man: Fannie Brand, an industrious girl who supports her brother and sister by working in a theatrical costume house, falls in love with Joe Halsey, a young fellow who earns a precarious living demonstrating an elastic exerciser in a drugstore window. Fannie and Joe set a date to be married, but the wedding is called off when Fannie finds Joe making love to her unprincipled sister, Edna. Fannie auditions for Landau, a theatrical producer, and goes on the Broadway stage. Fannie is a great success, and she and Joe soon find their way back into each other's arms.
