Plot

The distinguished chemical research scientist Nora Goodrich is postponing her marriage to her fiancé, Dr. Stephen Lindstrom, though her assistant and best friend Arline Cole advises her not to put him off too long. Nora takes home the materials to test on herself a new anaesthetic she has invented, which she predicts will induce vivid dreams and hallucinations before putting the subject completely under. It is a volatile substance, liable to explode into flame if improperly handled. On her way home, Nora backs out of her parking space and knocks down a woman named Jane Karaski who walked behind the car; Jane is not hurt and acknowledges that it was her fault, but a sleazy ambulance-chasing lawyer named J.W. Rinse gives his card to them both and tries to stir up a lawsuit.
