A priceless brooch, stolen from the ancient Russian house of the Vorontsovs was thought to be lost forever. Until Ekaterina Vorontsova-Lehrner, a descendent of the family, hatched a daring plan to take back what was rightfully theirs. Ekaterina, also known as K, learns that her successful heist hasn't gone unnoticed when she is confronted in the airport by Easy Man, a mysterious criminal fixer. With no other options, K is forced to travel to Brussels with one of the FBI's Most Wanted to meet with his client, Arthur Vornegut. The dangerous criminal mastermind, Vornegut, desired to possess the Imperial Diamond Necklace of Catherine the Great at an upcoming auction. But when K's exploits caused the auction house to cancel, and ruined his plans, he now aims to have her right this wrong or face deadly consequences. With only a short time to plan an impossible theft from Sotheby's priceless collection in Moscow, can K retrieve this prized object that will release her from Vornegut's ruthless grasp, or will she be betrayed and plunged into further peril by her unlikely accomplice who is strangely eager to help?
