Retelling the harrowing story of the death of a 16-year-old Manchester teenager. After witnessing a fight outside a pub following a 21st birthday party, Craig Rennie and Stephen Prince set off to walk home with friends around midnight. Shortly afterwards a car ploughed into the group, killing Craig outright and leaving Stephen seriously injured and in a coma. The driver, Michael Ganson, was a local man involved in the fight the boys had witnessed. He admits hitting the boys, but despite a previous conviction for driving directly at a police officer, Michael claims this was an accident - he was on his mobile phone while driving.

Shot from behind with a shotgun, 17-year-old Ashley Bowman 's death in July 2004 was the result of an apparently motiveless attack. The award-winning documentary series offering an insight into the criminal justice system follows the Greater Manchester police force's painstaking investigation as they discover that Ashley was killed by members of a small-time drugs gang in a tragic case of mistaken identity. Despite this information, no-one is willing to come forward and give evidence. Can the detectives break through the silence and secure a conviction?
