Two Egyptologists, Professor Fuchs (Keir) and Corbeck (Villiers), are instrumental in unleashing unmitigated horror by bringing back to England the mummified body of Tara, the Egyptian Queen of Darkness. Fuchs’s daughter, Margaret (Leon), becomes involved in a series of macabre and terrifying incidents, powerless against the forces of darkness, directed by Corbeck, that are taking possession of her body and soul to fulfil the ancient prophesy that Queen Tara will be resurrected to continue her reign of unspeakable evil.
