　　The series opens with Lizzie (Tahirah Sharif) returning to Farlow station where her boss and former lover, DI Kieran Shaw (Emmett J Scanlan), partners her with Arif Johar (Michael Karim). Their first call is to a domestic violence complaint against Mark Brannon, who is accused of beating up his girlfriend, Georgina Teel, and terrorising their young daughter Skye.
　　Lizzie persuades Georgina to tell the truth about what Brannon has done to her, enabling Lizzie and Arif to arrest him. However, once the case gets to court, Lizzie finds herself cross-examined on the stand, leaving the whole case on a knife-edge.”
　　Sarah knows that Fedden has handed her an impossible challenge, but she throws herself into it with typical determination and thoroughness. And, gradually, perhaps helped by the fact that she too was a teenager of Tania’s age back in 1997, she begins to uncover clues that previous investigations had overlooked. At the end of the first episode, Sarah’s investigations take a further twist, which means she and Lizzie cross paths again.

　　In Cobra: Rebellion Sutherland’s government is faced with their biggest challenge yet, but unlike the previous challenges they have faced, these threats come from much closer to home.

Embarking on a quest to discover the truth, they find something disturbing and disruptive underneath.
　　The crisis spirals to encompass not only the urgent threat of environmental destruction, but also the malignant corruption of the arms industry and the rise of shadowy corporate security firms. The cabinet are faced with the inconvenient reality of the UK’s historic relationship with a global superpower.
　　All these elements combine to lead our Prime Minister to a crucial decision, about who he is personally, and what – ultimately – he is willing to sacrifice in order to remain in power.
