While on a dig in Egypt, British archaeologist John Banning (Peter Cushing) desecrates the tomb of Princess Ananka, awakening her mummified lover (Christopher Lee). With revenge on his mind, the mummy follows Banning and the rest of his group back to England, but becomes quite taken with Banning's wife (Yvonne Furneaux), who resembles the princess quite closely.
