Documentary examining the stories of those most affected by the collapse of New York's World Trade Centre on September 11th 2001. As well as tracing the story of a family whose fire-fighter son hasn't been seen since he ran into the building on the day of the attacks, the programme tracks the recovery of Donovan Cowan, a young man who suffered burns to over 50 percent of his body in the towers. We are also afforded access to the recovery process of Renee Nolan, a pregnant mother on 9/11 who moved away from New York after her husband was killed in the attacks.
