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. Written by KGF Vissers

McG Missing in Action; Woe to the Virus **1/2
1 May 2012 | by (United States) – See all my reviews

Did Steve start his summer vacation earlier? His presence is sorely missing.

We recently viewed a similar episode about a virus running amok on Body of Proof. These epidemic episodes lack depth; there is almost a time-line where they have better find a solution to all of this or humanity is finished.

Involving NCIS in this matter just extends the excitement of multi-government agencies desperately trying to reach a solution.

Does our female police officer have a beau? Her cousin is trying to find this out, but she is even harder to move than the Rock of Gibraltar.
