Coals of Fire (1918)

Pretty young Nell Bradley is the daughter of a saloonkeeper in a "dry" town, and is looked down upon by townspeople, but Rev. Charles Alden, the town minister, finds himself attracted to her. One day at Nell's father's bar, a traveling salesman gets a young woman intoxicated, intending to "have his way" with her. Nell sees this and gets the bartender to save the young woman's virtue, but just at that moment Rev. Alden walks in and mistakenly believes that Nell has gotten the girl drunk. Complications ensue. - From IMDB
