At Duke's mansion in Madrid, Spain, Jackie is told of a story of German commander Hans von Ketterling and his regiment burying 240 tons of gold at a secret base in Africa's Sahara Desert before the end of World War II.

One night, while snooping around the home of one of the base's caretakers, Jackie meets Elsa, a young German woman, after saving her from two Arab men—Amon and Tasza—who also search for the gold.

After evading an army of black cars chasing him across town, Jackie is asked by Elsa to let her join his expedition, as she is in search of von Ketterling, who was her grandfather.

After another run-in with Amon and Tasza, Jackie's group returns to their camp to discover their comrades slain, but Momoko recognizes a statue in one of Elsa's grandfather's pictures and leads them to an ancient temple.

They discover the mummified remains of Elsa's grandfather and look through his log book, revealing that the 18 soldiers under von Ketterling ingested cyanide pills and died inside the base upon completion of their mission.

The man who uses the wheelchair—arriving with his mercenaries and holding Momoko hostage—reveals himself as Adolf, the 18th soldier who murdered Elsa's grandfather after the latter made him a paraplegic for refusing to ingest the cyanide.

Upon arriving at the vault, Jackie uses the key and a secret code from Elsa's grandfather's dog tag and opens it, revealing the elevator leading to the gold.

While Jackie battles the two mercenaries, Elsa and Ada flip random switches in the control room, activating the tunnel's turbine fan.

As the three men hang on for their lives, Elsa and Ada attempt to switch off the fan, but they accidentally trigger the base's self-destruct sequence.

Adolf tells the quartet that they can escape by having the turbine blow them through the ventilation duct, but he decides to stay to atone for his sins.

The quartet gathers as much gold as they can, but the wind force only sends their bodies upward to the desert surface above before the base completely caves in.
