Inspired by true events, Breach is a dramatic thriller set inside the halls of the FBI. When young Eric O’Neill is promoted out of his low-level surveillance job and into the headquarters of the Federal Bureau of Investigation, his dream is on the verge of becoming reality. But O’Neill is quickly confronted with the true reason behind his hire – Hanssen, a renowned operative, is the sole subject of a long-term, top-secret investigation, a suspected mole made all the more dangerous by the global import of the information he is charged with protecting. The Bureau asks O’Neill to use Hanssen’s growing trust and slowly draw the traitor out of deep cover. Engaged in a lethal game of spy-versus-spy, without the benefit of a cover story or back-up, O’Neill finds himself fighting to bring down Hanssen before the treacherous double agent can destroy O’Neill.
