Pretty Molly is afflicted with a peculiar nervous disease and after having tried many doctors is finally referred to a certain great specialist, who has had success with cases similar to her own. To briefly describe Molly's ailment would be in stating that the muscles of her throat and neck were uncontrollable, causing her to throw back her head in a way resembling a person beckoning to another. Molly goes to see the doctor, who expresses himself able to cure the case and prescribes certain medicine. But as Molly turns to go the unruly head is thrown back and the old M.D. is almost convinced the young lady is flirting with him. As Molly passes through the reception room where one or two young gentlemen are waiting to see the doctor, the peculiar nod is again repeated and the young fellows, each believing the nod to be an invitation, rise and precipitately follow her out. On the street Molly causes more excitement when she appears to solicit the company of a dignified lawyer, who, nevertheless, likes her looks and starts off after her until he is summarily dismissed with the threat of arrest for annoying a perfectly respectable young lady. An innocent mail man is the next victim, and he is similarly dispensed with. An old chap in the company of his wife is also beguiled by the unfortunate girl's peculiar nod and receives a sound berating not only from her but from his watchful spouse. Even Hans, the little bass drummer of the German band, is bewitched by the involuntary Circe and gets his drum smashed for his trouble. The climax comes when Officer O'Rourke falls a victim to the young lady's nod and is told that his services as a protector are certainly not needed. During the argument the captain, O'Rourke's superior, comes on the scene and orders the patrolman on his way. The girl has reached home and she thanks the captain for his protection. But as she opens the door those unruly muscles work again and the captain accepts the invitation. This is the last hope, and the poor girl slams the door in the captain's face.
