When a terrorist group led by the villainous Jacob Pearce attacks a high-profile embassy reception, with the French Minister of Defence as their target, protection officer Vincent finds himself working with street-smart MI6 operative Zara to save the day. But when events take an increasingly dark turn, Vincent and Zara soon realize that the plan extends far beyond just one politician. With suspicions that one of their colleagues in the security services is feeding information to Pearce, Vincent and Zara soon come to rely on each other more than either would have ever imagined. Increasingly isolated and with Pearce always one step ahead, can this unlikely pair stop Paris from falling to a man hell-bent on vengeance?
