The Devil's Own (1997)

In 1972, eight-year-old Frankie McGuire witnesses his father killed for being an Irish republican sympathizer. Twenty years later in Belfast, an adult Frankie and three other IRA members are engaged in a gun battle with the British Army and Special Reconnaissance Unit. One gunman is killed and another, Desmond, is wounded as Frankie and Sean Phelan flee. Hiding in the countryside, Frankie and his friend, Martin MacDuff, spot a British Army helicopter circling overhead and decide they need Stinger missiles.

Frankie travels to New York under the alias “Rory Devaney” seeking to buy missiles. IRA sympathizer Judge Peter Fitzsimmons has procured Frankie a construction job as a cover and arranged for him to stay with NYPD Sergeant Tom O’Meara, his wife, Sheila, and their three daughters on Staten Island. The O’Meara family is unaware of Frankie’s true identity. Meanwhile, Sean acquires a fishing boat that he and Frankie will repair to transport the missiles to Ireland. Frankie meets with black market arms dealer and Irish mobster Billy Burke, who agrees to purchase the missiles using his own money.
