Pharaoh Khufu (Jack Hawkins) has amassed a fortune in gold and jewels through many years of war. His intention is to have all of his wealth buried with him, but worries about grave robbers. He commissions a recently acquired slave, Vashtar (James Robertson Justice), who is also a master architect, to design and build an impregnable burial vault within his pyramid. Meanwhile, an attractive young woman from Cyprus, Princess Nellifer (Dame Joan Collins), is sent to Khufu as tribute. She soon becomes his favorite and his second wife. When she sees his treasure, she has every intention of obtaining part of it for herself.
