On an expedition to Egypt, Professor Fuchs discovers the tomb of the beautiful Queen Tera, legendary Queen of Darkness, whose power was reputed to stretch beyond the grave. He returns to London, bringing with him the queen's mummified body, her severed hand which still oozes blood, and other objects from the tomb. From that moment on, strange things begin to happen to Fuchs and his team, as the objects seem to take on a life of their own and possess the power to strike down anyone who crosses their path. Most vulnerable is his beloved daughter Margaret, who has begun to bear an uncanny resemblance to the long-dead Egyptian queen.
