Erin's finding it increasingly hard to keep working on the Stone/Mervich case. The gruesome brutality of the crime keeps seeping into her waking and dreaming life. So when Rhys suggests she drive with him to view the crime scene, Erin is terrified, and tries to hand over the case. Janet gives her an ultimatum, and Erin concedes to a go out to the farmhouse with Rhys. But when she gets there, it all proves too much. After Rhys takes her to a hospital, they have a close encounter in a swimming pool. Murray Rice taunts David that he isn't man enough to prosecute the AG. David rises above it, but later requests a copy of the file from Tracey. What he sees will force a big decision onto the DPP.

The scan has shown the slight possibility of profound foetal disability in one of the twins, leaving the couple split on this life-changing decision. Tony and Tatum are pushed together on a mercy killing/medical murder case. The husband of a woman, suffering from motor neurone disease, believes she was murdered by a deliberate overdose of morphine. Meanwhile, Lina and Paula's friendship blossoms.

The investigation into Max Gardiner takes a turn when Max's father gives evidence about his abnormal behaviour. As more information is uncovered about Max's history, Lina forms a firm opinion on his guilt. While Janet recommends not prosecuting, David has his own ideas – and forces Janet to pursue Max in court.
Richard is surprised when Tina Chang discharges herself from hospital, intent on giving evidence to shut Vatalidis' killer away for good. But she soon starts to crumble when faced with the prospect of giving detailed evidence of her ordeal in court. Richard does all he can to calm Tina down – but unwittingly crosses the line, forcing Tracey to take him off the case. Unable to face court without Richard, Tina follows him on a night out – and guilty Richard is forced to put her straight. But he's unprepared for the shock news the following day that Tina has fled the country and will not be giving evidence.
