17-year-old Johnjo (Nico Mirallegro) gives his cousin Tony and his mates Colin and Kieran a last minute lift in his brother Patrick's car. They tell him they're going for pizza; Johnjo doesn't know that they're going to 'have a word' with a local loudmouth who needs putting in his place. As Johnjo waits in the car, Kieran takes offence with an innocent bystander, Thomas Ward, who is fatally stabbed. The murder victim is the eldest child of Margaret (Susan Lynch) and Tommy Ward (Daniel Mays), who has become estranged from his family after a bitter divorce. Struggling to make ends meet on her own, Margaret is nevertheless determined to fight through bureaucracy and the cool indifference of the banks to give Thomas the send-off he deserves. Johnjo makes his own way to the police station and asks for DI Hastings (Robert Pugh). A career copper used to doing battle with 'no comment', Hastings can't believe his luck as Johnjo lays the blame squarely with Kieran. But Hastings wants everyone possible to be tried for murder, and with the joint enterprise doctrine at his disposal, that includes Johnjo.
