The Boston Marathon bombing serves as the starting point for this report, which walks through the timeline of the attack and the manhunt that followed for the Tsarnaev brothers. Rather than treating the case as closed, the film raises a series of questions about inconsistencies in the official account, revisiting witness statements, security footage, and law enforcement press conferences that surrounded the bombing and its aftermath. It presents itself as an investigation into what actually happened at the finish line and in the days after, rather than a straightforward recap of news coverage. The tone is skeptical of the official narrative, though it works from real footage and documented events rather than speculation alone. Viewers get a compressed account of one of the most heavily scrutinized crime scenes in recent American history, framed around the gaps its makers believe remain unresolved.
