Three Days of the Condor
A bookish library clerk working for a CIA front is hunted after he stumbles across a covert intelligence operation. Returning from lunch, he finds the entire office massacred. Using his codename Condor, he contacts the CIA, but when an agent tries to kill him, he kidnaps a stranger off the street to ensure his survival and attempts to turn the tables on those who want him dead.
