Code named "The November Man", an extremely dangerous and highly-trained ex-spy (Pierce Brosnan) is lured out of retirement to protect a valuable witness (Olga Kurylenko) who could expose the truth behind a decades-old conspiracy. His mission is compromised when he becomes the target of his former protégé (Luke Bracey) and, with growing suspicions of a mole in the agency, there is no one he can trust and nowhere to hide.
