Shot on location in Egypt, the story unfurls like an Italian Giallo as a group of people meet under strange circumstances, and one by one they are murdered. Gold is missing so you suspect a thief is trying to cover up his crime but that might be too obvious.
Unfortunately the movie Secret of the Sphinx is not yet available on HBO Max.
