Yesterday marked one full year since the horrific Boston bombings which killed three people and injured 264 others at the finish line of the Boston City marathon, culminating in a manhunt which shut down most of the city. This documentary tells the story of those five days of terror last April, with access to the FBI, police, the injured and those who were caught up in the biggest manhunt of recent times. Featuring interviews, dramatisations and a look at the key moments in the decision-making process that led to the release of photographs of the suspects.
