A baby called Jake Osbourne is kidnapped and a major investigation begins. Norton doesn’t think the baby’s name is a coincidence, and suspects that Wicklow is involved. Jake is brought in to help with the investigation, something Eve resents following their break-up.
The team is convinced that Wicklow is finally planning his revenge upon Jake. He’s dying of cancer and it’s his last chance. News of the kidnapping and of Jake’s involvement in the case becomes known to the press, and a media feeding frenzy begins. This leads to Jake’s son, Joss (Will Roache), finding out the truth about his father from a journalist. Jake seeks out Joss to explain, but is beaten up by him in a ferocious attack.
Wicklow’s sister, Barbara is identified as a suspect. The team are now convinced that Wicklow has masterminded the whole thing and that Barbara has the baby. The team search her home, but she’s nowhere to be found. However, the search leads to a shocking discovery, a 40-year-old dead baby wrapped up in an old party dress.
Wicklow is delighted by all the attention he receives when the police question him in hospital. As expected, he gives nothing away. The police decide the only way to lure Barbara out is to announce that he only has hours to live. Their plan works and Barbara appears. She’s interrogated by police but tells them nothing, while tests reveal that the dead baby was still-born, so no charges can be brought. Barbara is released but put under surveillance, which she evades.
Losing Barbara is a major police failure. They’re now at a loss as to what to do and are horrified when they discover that Joss has gone missing. The police fear he’s been kidnapped by Barbara along with the baby.
Barbara has drugged Joss, and leaves him overnight at the hospital mortuary. Wicklow uses a modelling blade he smuggled out of prison to cut off his thumb and enable him to escape from his hospital bed. As the alarm is raised, Wicklow makes his way to the mortuary.
Barbara is on the roof of the hospital, dangling the baby over the edge. Norton desperately tries to persuade her to hand the baby over. Barbara does so, but has nothing to live for now that Wicklow is dying and jumps to her death.
Eve and Jake reach Wicklow in the mortuary. They beg Wicklow not to kill Joss, Eve tells Wicklow that Barbara couldn’t go through with killing the baby, following the death of her own baby all those years earlier. Jake realises that Wicklow was the father of Barbara’s dead baby.
The revelation weakens Wicklow and he loses control. Eve tries to disarm him, but he grabs her and cuts open her throat. Jake then stabs Wicklow, once again becoming the killer he swore he never would be.
