Movie plot title: Ronin Movie plot: At a bistro in the Montmartre district of Paris, IRA operative Deirdre (Natascha McElhone) meets with ex-special operatives-turned mercenaries Sam (Robert De Niro) and Larry (Skipp Sudduth), both Americans, and Vincent (Jean Reno), a Frenchman. She takes them to a warehouse where fellow mercenaries, German Gregor (Stellan Skarsgard) and English Spence (Sean Bean), are waiting. There, Deirdre briefs the men on their mission: they have been hired to attack a heavily armed convoy and steal a large metallic briefcase, the contents of which are never revealed. As the team prepares, Deirdre meets with her ex-IRA handler, Seamus O'Rourke (Jonathan Pryce), who reveals that the Russian mob is bidding for the case and the team must intervene. After Spence is exposed as a fraud by Sam and summarily dismissed, the others depart for Nice. Sam and Deirdre develop an attraction to each other during a stakeout. On the day of the sale, Deirdre's team ambush the convoy at La Turbie and pursue the survivors back to Nice. After a gun battle at the port, Gregor steals the case and disappears. Gregor tries to sell the case to the Russians, but he is forced to kill his contact when he betrays him. He then contacts Mikhi (Feodor Atkine), the Russian mobster in charge of the deal, and makes him agree to another meeting. The rest of the team later track Gregor through one of Sam's old CIA contacts and corner him in the Arles Amphitheatre, where he is meeting two of Mikhi's men. Gregor flees but is captured by Seamus, who kills Larry and escapes with Deirdre. Sam gets shot saving Vincent's life and is taken to a villa in Les Baux-de-Provence owned by Vincent's friend Jean-Pierre (Michael Lonsdale). After removing the bullet and letting Sam recuperate, Vincent asks Jean-Pierre to help them locate Gregor and the Irish. Back in Paris, Gregor is brutally interrogated into leading Seamus and Deirdre to a post office, where they retrieve the case. Sam and Vincent pursue them in a high-speed chase, which ends when Vincent shoots out...
