A young English lord, who has been excavating in Egypt, finds a mummy of a beautiful Egyptian princess, more than 5,000 years old. So well has the Egyptian embalmer done his work that the face is perfect in all its beauty, and the susceptible young man falls deeply in love with this belle of old Egypt, takes the mummy home to his estate in England and there it occupies his whole mind, to the exclusion of all else. Even the proposed visit of a beautiful American girl does not arouse his interest. In his sleeping moments he dreams that his mummy is alive and that he also is a subject of the Pharaohs. The mummy so works on his mind that he is losing his reason, but it is ultimately saved by the appearance of the American girl, who so resembles the mummy that she seems to be its reincarnation.
