On 7 July 2005, four suicide bombers attacked London’s transport system, causing carnage and bringing central London to a standstill. Fifty-two people were killed and some 770 wounded. It was deemed the deadliest attack on the capital since the Blitz. But this isn’t just the story of a terrorist atrocity: it’s also a story of bravery, compassion and the astonishing resilience of the human spirit told through the vivid eyewitness testimony of both those involved and the families and friends affected by the tragedy. Narrated by Mark Strong, this powerful documentary was made to commemorate the tenth anniversary of the day that’s been dubbed ‘Britain’s 9/11’.
