South of Algiers

Doctor Burnet (Portman) is obsessed with finding the legendary and priceless Golden Mask of Moloch. It is believed to be buried in the lost tomb of a Roman general somewhere in the Algerian desert. Burnet is dubious of Nicholas Chapman's expertise and good-faith, but agrees to let him join the party. Unknown to them, Burnet and Chapman are accompanied on their flight to Algiers by unscrupulous fortune hunter Petris (Charles Goldner) and his sidekick Kress (Jacques B. Brunius) who are just as keen to get their hands on the mask.
