Dummy inventor Samuel Tinker has just developed a new life-sized mechanical dummy. He and his partner, Peter Clay, modeled the dummy after a janitor in their building. While the inventor's daughter is in love and engaged to Clay, the janitor pines for the daughter. But the daughter hopes a possible lucrative purchase of the dummy from a vaudeville company will be the impetus for her father and Clay to mend their differences, and for them again to be married. The janitor, who sees this rift as an opportunity, hatches his own plan to be near the one he loves.
