Born in Russia, Jetta was active as a revolutionary in the late 19th century, plotting against a tyrannical Tsar (alluded in the game manual to be a relative of hers). She was forced to flee to Indonesia, where she learned the fighting style of Pencak Silat to add to her knowledge of Savate. Going undercover as a circus acrobat in China, she met with other revolutionaries and planned a return to Russia. However, agents of the Tsar caught up with her and arranged for an untimely 'accident', witnessing her fall from the tightrope without a net.
