On the eve of Bastille Day in Paris, American drifter and pickpocket Michael Mason steals a woman's handbag, not knowing that it contains explosives.

The bomb was set up by a group of corrupt policemen, all of them members in the French special police RAPID unit led by Rafi Bertrand, who intend to pull a robbery at the Bank of France.

Zoé was told to plant the bomb at the office of the French Nationalist Party (as part of a diversion for the heist), but after seeing the night cleaning crew arrive, she was unwilling to kill innocents and so abandoned the plan.

Bertrand's team proceeds to plant fake evidence at a mosque and stir up a nationwide uproar among its Islamic population, using agitating hashtags on the Internet.

Chased by the French authorities and Bertrand's forces, Mason is picked up by Briar, who has come to believe his story and intends to clear the case with his help, even against the orders of his superiors.

Briar informs his colleague, Karen Dacre, who confers with her French contact, DGSI Director Victor Gamieux, about taking Mason and Zoé into protective custody.

When a crowd of protestors masses at the front of the bank – as the conspirators have intended – Gamieux assigns Bertrand's RAPID team to the building to provide interior security, thus facilitating the digital robbery of its entire monetary reserves (half a billion euros).

Hearing of his predicament over their stolen police van's radio, Zoé and Mason start a riot among the protestors, who storm the bank and overpower the RAPID officers closing in on Briar.

Sometime later, Mason, working with Briar and French law enforcement, meets with Gamieux on the pretense of trading the flash drive for a passport and a ride out of the country, leading to the latter's arrest.
