Harold is ensnared by the wiles of Sybil, an adventuress. The boy forgets Helen, his country sweetheart. Sybil’s influence over him is so evil that he can no longer apply himself to his work. His employer finally discharges him. When Harold’s money is gone, the adventuress throws him over. He becomes a drunkard. Helen, failing to hear from him, comes to the city, where she secures a position. Harold decides to become a hold-up man. To pass away the time before midnight, he goes to a theater where Bert French and Alice Eis are presenting their famous “Vampire Dance.” The characters are an artist and a vampire, in the guise of a wood nymph. Harold sees the artist attracted by the beautiful creature and then his struggles as he realizes what the result of the fascination must inevitably be. The victim beats her in his frenzy of fear, but is irresistibly drawn into the coils by the vampire’s fiendish wiles. The vampire fascinates the man by her beauty and lures him toward a forest dell There the horrible creature succeeds in taking his life. Harold feels that a veil has been torn from his eyes. He seems to have reviewed his life with Sybil, and vows to reform. He succeeds in regaining his position and once more takes his place among men. The boy learns of Helen’s presence in the city, but can find no trace of her. Sybil, learning of Harold’s prosperity, attempts to drag him into her net once more, but the boy, with the memory of “The Vampire Dance” before him, resists her efforts. That night he finds Helen, and to insure his reformation, proposes immediate marriage. His sweetheart consents, and the knot is tied.
