At a medical conference in Prague, American scientist Dr. Fiona Devin is contacted by one of her Russian colleagues. Dr. Valentin Petrenko, a specialist in rare diseases, is concerned about a small cluster of deaths in Moscow but even more concerned by the Russian government's refusal to publicly release any data on the outbreak. When he meets with Devin to pass on his case notes and medical samples, the two are attacked, Petrenko killed while Devin barely escapes with the notes and samples. Lt. Col. Jon Smith, in his role as a Covert-One operative, is dispatched to Prague to get Devin and her information safely back to the U.S.
