A Flemish Christian knight named Charles Le Vaillant (Jean-Claude Van Damme) becomes demoralized by the horrors of war and decides to create a new religious order.

The last chapter from their religious text, buried by Le Vaillant in a secret place, becomes lost in the desert after the attack.

In the modern day, Rudy Cafmeyer (Jean-Claude van Damme), a thief and smuggler of valuable historical artifacts, breaks into a high-security building and steals a precious Fabergé egg.

Ozzie's associate, Professor Walt Finley (Charlton Heston), gives Rudy the key to a safe-deposit box in East Jerusalem before being gunned down by unknown assailants.

Rudy opens the safe-deposit box and finds an ancient map showing a series of tunnels and a treasure room beneath Jerusalem.

Rudy hides from the police and is found by Lt. Barr, who drives him to be helped back to health by her old friend Avram, who is still a member of the Order.

Rudy shows it to Avram, who insists that the "treasure" is merely a metaphor for the wisdom of the ancient sages and says that its location in the Order's monastery cannot be accessed by outsiders anyway.

Rudy saves Avram from falling into a pit trap before they reach a room loaded with treasure next to the chamber underneath the Well of Souls.

Ben Ner attempts to delay the detonation in order to collect more treasure, leading to a standoff with Cyrus's followers.

For me the highlight of that movie is the chase through the Old City of Jerusalem, with Van Damme disguised as a Hasidic Jew, running from and fighting with the Israeli police.
