Alice and Jack end up getting busted along with their dope fiend buddies. While Jack goes down for two years, Alice gets a year and emerges from prison a reformed woman, ready for a fresh start.
Alice moves to a new area and gets work in a hospital experiencing a nursing shortage (certainly true to life there), where she and the doctor in charge soon fall in love with each other, he proposes, and she says "Yes", despite the nagging worry over what he'd say if he knew about her troubled past. Alice gets promoted to anesthetist, and things are going well until the cops bring in the wounded Jack Dillon, and Alice is faced with the possibility that Jack will expose the truth about her, and she'll lose the doctor she's about to marry.
Alice has the power of life and death in her hands as she administers the anesthetic to Jack, and succumbs to the temptation to take the easy way out and give him just a little too much ether and silence him forever. But at the crucial moment her conscience wins out, and she withdraws from her plan to kill Jack only to see him die on the operating table. Feeling intense guilt, Alice runs away, but Dr. Mark Gibson gets to the railroad station just in time to prevent her flight. She comes clean about her past, and about her thoughts of murdering Jack, but Mark explains that Jack was already dying when he came into the hospital, his internal bleeding leading to his final death, nothing to do with ether. Mark absorbs and adjusts to this new information about his fiancee rapidly, and the wedding is still on! It all goes to prove that the reformatory powers of our criminal justice system can even help those weak-willed nurses with their hands in the medicine cabinet, and doctors are above the petty stigmatizing that the rest of us mortals in society sink to when we discover someone has a criminal record.
