Her Better Self (1917)

Even though society debutante Vivian Tyler (Pauline Frederick) is engaged to Count Belloto (Frank deRheim), she finds herself attracted to Dr. Robert Keith (Thomas Meighan). Keith works amongst the poor, and his wealthy benefactors include Vivian's father (Charles Wellesley). But when Vivian meets streetwalker Aggie May (Alice Hollister), she mistakenly believes that Keith is responsible for the woman's downfall.
