Still struggling with grief, Kate works with Michael to defend Alice Munezero from the charges laid against her in France. As shadowy forces try to prevent the truth being unearthed, Kate faces threats to her personal safety. Meanwhile Michael struggles with his health back in London. Can they both continue forward to gain an acquittal for Alice?

Kate and Michael finish their work on Alice's case in France but are shocked when an indicted Rwandan and Congolese war criminal, Patrice Ganimana, implicated in the Genocide, arrives in the UK. Excited by the chance to prosecute him, Michael is unsettled to learn that an old rival is handling his defence. Meanwhile this new arrival prompts Alice Munezero to delay her own return to Rwanda. As difficulties multiply for an extradition of Ganimana to the International Criminal Court, Kate and Michael's relationship begins to fray.

Patrice Ganimana's warnings about Kate's safety are borne out when Kate and Alice are both attacked. But Kate, nevertheless, continues her search for the case file her mother had prepared against Ganimana years before. But are establishment forces somehow closing ranks to impede bringing Ganimana to justice?

Kate and Florence return to the UK to continue the search for Eve Ashby's case file against Patrice Ganimana. But someone is ahead of them, stopping at nothing to kill and terrorise their way to the missing evidence. Meanwhile Michael in the UK, Alice Munezero in Rwanda and Eunice Clayton in the US believe the time has finally come to reveal the truth about a long-buried crime, which in turn exposes Kate to a dark truth about her own past.

In Rwanda, Alice Munezero languishes in custody. In the Democratic Republic of Congo, Kate fights against hostile locals as well as international forces to prove the truth of her personal history. Meanwhile in London, Michael delves into a deep political and financial conspiracy. Can he expose this in time, while Kate fights for her very life in an explosive climax?
