The story about the murder of a 11-year-old boy, Rhys Jones in Liverpool, in 2007 and his parents, Melanie's and Steve's ordeal, and how Rhys's murderer and associates were eventually brought to justice.
In 2007, 11-year-old Rhys Jones is inexplicably shot dead walking home from football practice. Newly-promoted Detective Kelly leads the murder inquiry.
As Rhys's family attends his funeral, the suspects dispose of anything to incriminate them. With nothing to discredit the gang, Detective Kelly still has no clear evidence to make an arrest
Detective Kelly believes he has a lead when a young boy, encouraged by his sister, admits to the police that Rhys' brother gave him a gun. But the lead prosecutor still feels there is insufficient evidence to proceed.
