Complete story — includes the ending
On a Siberian train, Lukas Basarov detonates a prototype Micro Pulse Bomb which leaves equipment intact, but incinerates a politician and laborer playing chess, and two others passengers. An MI-6 double agent is suspected. Through an old contact, his MI-6 counterpart Elizabeth Powell, Jack learns the identity of the MPB designer, Basarov. Rachel goes to a " geek " conference in São Paulo, Brazil to tap Basarov's laptop. Under the alias "Bob Brown", Julian Sark is on the same "freelance" mission for his client. Both are successful, and after a few drinks they go back to Sark's room for sex. In Málaga Spain, Jack and Elizabeth witness an arms transaction of a much larger MPB. Instead of identifying the double agent, it ends in an ambush by Benjamin Masari, head of the Sudanese RLF terrorist squad, who steals the weapon, and takes Jack and Elizabeth prisoner, moving them to Tunisia. The team discovers Sark was the leak. Having seen his travel plans, Rachel and Sydney go to Nassau, Bahamas to hire him. Sark arranges to buy the prisoners from Masari, but he's double-crossed and handcuffed to the MPB. Dixon and Grace kill Masari's men. Remotely, Marshall helps Rachel disarm the MPB.
