Overview: A scientist of an enemy power, Dr. Oswald Beck, has developed a bacteria which causes cerebral spinal meningitis and mutated it into a form that kills and then becomes inert after a few hours. The IMF must destroy the preliminary culture and stop Beck. Rollin replaces the prisoner chosen for a test of Beck's bacteria, and Barney switches the bacteria cylinder for one with knockout gas and then uses a balloon to capture the gas. Rollin ""dies"" but then Jim, who has infiltrated the base as a military medic, ""discovers"" that Rollin isn't dead. Meanwhile, Barney releases the knockout gas into the control room, knocking out Beck's superiors. Beck thinks they are dying from his bacteria and believes they'll think he's a traitor who tried to kill them rather than the test subject. He flees but is shot while Jim destroys the bacteria.
