Complete story — includes the ending
A French satellite crashes into Russia and almost triggers a nuclear war. ECHELON picks up a call indicating that Sark is involved. Sydney travels to Mexico City to spy on Sark, who is meeting with dishonorably discharged Russian space command general, Boris Oransky. After discovering their plot, she and Vaughn go to Moscow to assess the bunker under the Science Ministry to steal Medusa, a pulse weapon capable of crippling satellite networks, before Sark gets it. The NSC assigns Loren to investigate Lazarey's death. Jack corrupts the security camera image to stop Sydney from being identified as Lazarey's killer.
