Gone Baby Gone is a 2007 American neo-noir mystery film directed by Ben Affleck (making his feature-length directorial debut) and starring his brother Casey Affleck. The screenplay by Ben Affleck and Aaron Stockard is based on the novel of the same name by Dennis Lehane, author of Mystic River and Shutter Island. The plot centers on two private investigators, Patrick Kenzie and Angie Gennaro, hunting for an abducted four-year-old girl from the Boston neighborhood of Dorchester. Wikipedia
(first lines) Patrick Kenzie: I always believed it was the things you don't choose that makes you who you are. Your city, your neighborhood, your family. People here take pride in these things, like it was something they'd accomplished. The bodies around their souls, the cities wrapped around those. I lived on this block my whole life; most of these people have. When your job is to find people who are missing, it helps to know where they started. I find the people who started in the cracks and then fell through. This city can be hard. When I was young, I asked my priest how you could get to heaven and still protect yourself from all the evil in the world. He told me what God said to His children. "You are sheep among wolves. Be wise as serpents, yet innocent as doves."
