The plot is laid out like puzzle pieces scattered around the globe. The CIA's dirty secrets have been exposed, leading top director (Edward Norton) to order all evidence extinguished, including the spies themselves.

A PhD in genetics would have made the medical jargon go down a lot easier -- but it rarely detracts from the action.
