Sheik El Sahid has built a theme park at the underground holy City of the Dead in Egypt that an earthquake has revealed. Two American publicists are brought over to make it a success, to advertise its fantastic mechanised speaking mummies. The place soon appears to be cursed especially when the ancient mummies begin breaking free and wreaking havoc.

Set in Europe during WWII, a group of American soldiers on their way to military prison are beset upon by a German artillery attack, escaping with Switzerland in their sights. Before making it any farther, they volunteer to steal a V2 warhead for the French Underground - taking them deep into the heart of German territory.
