From the Ground Up (1921)

Refusing her father's request to marry young Carswell, daughter Philena can't stand him, but in order to insure a loan Mr. Mortimer needs to complete construction of an office building. As a result, her father is ruined financially. While the building site is being excavated, Philena is attracted to Terence Giluley, a pick-and-shovel man who is forced to exchange with her his harmonica for a dollar bill. The act inspires him to work harder and rise to her social level, and soon he is promoted to contractor. Philena decides to sell her horse to aid her parents, and Terence offers her $500 for it, but on a last ride the horse is injured and has to be killed. Philena and Terence meet again while attending night school; she appears among applicants when he advertises for a stenographer; Terence proposes marriage to her and is accepted.
