Gibbs is surprised that he must pick a man, Mcgee, to escort brilliant ITC colleague Kevin Hussein, who repatriates his uncle, a professor who died in Moskow. Despite a warning from the Russian government, late terror brain Ari Haswari's national 'fan club president' Yiri mobilizes a team to shoot down the US helicopter on its way to Finland. Suspicious about the Russian lack of cooperation or even disclosure, the home team discovers that the corpse was already repatriated, perform an autopsy and find a memory device inside. Before Gibbs can warn Abby, as Kevin came clean, it spreads a virus despite normally sufficient precautions. Gibbs' party must fight and run for their lives to reach Finland.
