Don't look for a happy ending. It's not an American story. It's an Irish one.
Brad Pitt plays Frankie 'Angel' McGuire a wanted IRA soldier who is sent to New York City from Northern Ireland to purchase a massive amount of weapons. Harrison Ford does a good job, as the sympathetic New York cop who takes in the IRA gun runner in having no idea of his past. Is his Ford going to find out who Angel is or what he is planning to do! Well you'll have to see the film to find out.
It's well paced with decent acting, Brad Pitt's accent aside. The movie twists you emotionally in a way that few films can. You connect with the two main characters, and you grow to like them and find yourself getting involved in their story. Worth watching!
I'll end it with a quote that reinforces this movie and one that I believe "One man's terrorist is another man's freedom fighter"
