FBI allocates Eric O'Neill, a fresh and young FBI employee to work under senior Robert Hanssen.
Hanssen, who has been working with the FBI for 15 years and is given the duty of guarding America's most sensitive documents, is believed to be a Soviet Union spy.
Initially O'Neill is told that he is to monitor Hanssen's weird habits. However, it doesnt take him long to realize that the real reason behind monioring Hanssen was to find evidence about Hanssen selling American secrets to the Soviet Union, which in turn had led to the death of many.
After a long escapade of marking every single of Hanssen's moves, O'Neill and the FBI manage to catch Hanssen red handed while trying to send a secret document at the Virginia Park.
The movie is attention grabbing from beginning till the end. The part where O'Neill tries to get data out of Hanssen's palm pilot is perhaps one of the most intersting scene in the movie.
