In 1895, a team of archaeologists uncover the tomb of Princess Ananka, an Egyptian high priestess. They are warned not to disturb the tomb but in doing so, inadvertently bring to life the mummy of Kharis, the high priest who loved the Princess. While in the tomb alone, something happens to frighten the leader of the expedition, Stephen Banning. Three years later an Egyptian, Mehemet Bey, transports the mummy to England to seek revenge against those who desecrated the Princess' tomb. It is left to Stephen Banning's son John to unravel the mystery and to protect his wife Isobel, who bears a striking resemblance to the Princess.
