Woman-Proof (1923)

Tom Rockwood's brother and two sisters attempt to induce him to marry so that they may inherit money left to them by their father. Rockwood, a civil engineer, rescues Louise Halliday, a family friend and ward of Bleech, the Rockwood family lawyer, from a blasting site, and he is so attracted to the girl that he determines to marry her. Bleech attempts to break up the couple because he has nefarious plans for the money, but he fails, and Tom and Louise marry on the last day allotted to them by the will, thereby saving the family fortune.
