A bloody hotel room and a stolen credit card lead Ronnie and Joe to Charles Hutton, a member of the wealthy upper-class who dotes on his wife Camille, and daughter, Georgia. Without a body it's difficult to ascertain the crime, but before long, Ronnie and Joe have enough evidence to suggest that Georgia gave birth in the hotel room – but where is the baby? Georgia and her boyfriend are difficult enough for the CPS to prosecute but to make matters worse the defence counsel turns out to be an old nemesis of Jake's, Maitland Cosby. But as the evidence against the young couple stacks up, how far will Georgia's father go to protect her future?

After a fatal stabbing in a crowded market place, the pressure is on to make Londoners feel safe again. Ronnie and Joe have a new boss to contend with, DI Elisabeth Flynn is determined to put her stamp on the MIU, declaring her own personal crackdown on knife crime. Under pressure from all sides, Ronnie and Joe struggle to gather enough evidence to charge the youth they believe to be responsible. However, when the suspect inadvertently confesses to Ronnie, he thinks he's got him – but with the confession uncorroborated by anyone else, Ronnie begins to realise that his honesty is in question.
