A new drama set in the East End of London in 1889 during the aftermath of Jack The Ripper murders. The infamous H Division – the police precinct charged with keeping order in the district of Whitechapel- is in a chaotic state trying to keep order after a tumultuous time for London and reported infamously worldwide. Reid must return to Whitechapel to covertly re-investigate a case apparently solved by Drake and Jackson, while Susan receives devastating news. Reid struggles to adapt on his first day back at H Division under Drake’s command, and immediately finds himself at the helm of a baffling case. The investigation into a bloody double murder threatens to expose Jackson’s recent illicit activities, while Susan takes charge. When a footballer is brutally murdered, a key suspect is a man close to Drake’s heart, which forces Reid to conduct a clandestine investigation, while Susan hatches a plot. Drake’s life begins to unravel as he questions whether he sent an innocent man to the gallows, and Rose struggles to convince anyone about what she saw.
