A terrorist cell infiltrates the NorBAC lab and forces the scientists to produce a deadly measles mutation to be used as chemical warfare.
Well, the series end is near, and they are taking out all the stops. While I HATE HATE HATE to reference wikipedia as a source... they have a GREAT definition of what a "bottle episode" is. This episode had no location shoot besides our NorBAC lab (and a shot of David's apartment). This made the whole episode feel familiar yet closed and claustrophobic. After a long and tense standoff between our heroes and the baddies we find that one team member did not make it out. Rachel, I can't say I'll entirely miss you but you went out like a champ.
