The documentary charting high-profile crimes committed by young people concludes, highlighting instances involving individuals who were described as 'feral youths', acting in wildly undisciplined and anti-social ways. The cases featured are the murder of 27-year-old fish factory worker Lukasz Rzeszutko, who died after 19-year-old Martin Morgan assaulted him and proceeded to 'dance' on his head for the amusement of his friends. The programme also revisits the murder of 19-year-old David Byrne, who was lured to his death by a number of youths sending text messages pretending to be a girl, before he was chased and cornered by 17-year-old Marcus Kirwan, who proceeded to stab him nine times. Both killers denied any involvement in the deaths, but were found guilty by their respective juries.
