On 30 January 1972, the British Army deployed the 1st Parachute Regiment to conduct an arrest operation in Derry, during a Northern Ireland Civil Rights Association march. During the protest, fourteen unarmed marchers were shot and killed by the regiment and another fourteen were seriously injured. The day has since been known as Bloody Sunday. Two investigations have since been held by the British Government. The first largely cleared the soldiers of any wrongdoing; the second, brought about by the determination of teh victims' family members, has yet to report a conclusion."Before Sunday" is a touching portrait of the victims' lives before that tragic day. We are introduced to a photographer, a golfer, a student, a prankster, and ten other boys and men who we learn are very much like our own fathers, sons, brothers, and friends.
