The lead is the tortured female detective Elizabeth Bancroft with dark secrets in her past. She is running an operation against a vicious drug gang, Kamara, and adopts dubious methods to bring down the brothers who run it.
But then she becomes distracted by DS Katherine Stevens, who is investigating a cold case in which Bancroft was involved.
