On September 1, 2004, hundreds of students of all ages arrived with their families at School No. 1 in Beslan, North Ossetia-Alania, Russia for the start of the school year. The first day of school was a celebration punctuated with music, poems, and videos. But this year would be different. This year's Day of Knowledge festivities, however, wouldn't end in the first ringing of the school bell, but with gunshots.
