As Nina lies in hospital Jack works out that Sarah could not have shot her whilst Sarah's supposedly dead husband Latif tells her that he did not kill Amir. Waite, however, sees him a a prime suspect and Amir's brother Kamal also agrees that the couple are murderers, before he too is killed. As a result Sarah aims to leave the Jihadis, who are planning an attack on a particular building and in thwarting it the police and pathologists must discover the link between Latif and Kamal and save another anti-fundamentalist opposed by Sarah.
