In September 2004, armed militants seized School No. 1 in Beslan, North Ossetia, taking more than a thousand students, parents, and teachers hostage on the first day of the school year. The siege ended two days later in chaos and explosions, leaving over 330 people dead, many of them children. This film revisits the standoff through survivor accounts, security footage, and interviews with officials and journalists who covered the crisis, tracing how the Russian government's handling of the negotiations and the final assault has never been fully explained. It examines the conflicting accounts of what triggered the first explosions inside the gymnasium, the delayed and disorganized rescue effort, and the grieving mothers of Beslan who have spent years demanding an independent investigation. Rather than settling on a single version of events, the film lays out the competing narratives side by side, leaving the central question of what really happened inside that school unresolved.
