Ishmael, the son of Hagar, an old hag, living on the edge of the desert, falls completely under the charms of Lispeth, a vampire. One day there passes the miserable hut in which these three strange people live, a wealthy banker, named William Corday, his wife and son. Derrick. Lispeth wields her magic power over the husband and soon has him in her power. When he attempts to kiss her, she repulses him. So clever is she that the wife has no idea of her husband's unfaithfulness.
