A veteran who collapses fatally while attempting to visit his son despite restraining order is diagnosed with bubonic plague, even worse, a war lab variation which spreads much faster, which seems to be tested on unsuspecting social outcasts. Steve remaining traceless on his Sheldrake expedition to Japan, Danny takes charge. As the case links to the Rumanian gang lord Dracul Comescu, Callen's kin's nemesis, Five-O teams up with his NCIS LA team. Although they get the better of the Balkanic fiends, the hemorrhagic killer virus leaves the island to LAX and the bacteriology mastermind remains at large.
