Whitechapel 1888; a killer is on the loose and the newspapers are ensuring the nation knows all about not just the crimes but the terrible living conditions in which they are being perpetrated.

Nashey, a tough, scary yet charismatic man of the night, whose mother had to prostitute herself when he was a boy, knows the identity of the killer but keeps it a secret. He believes the publicity generated by the murders is forcing the authorities to address the poverty and degradation in the area. He allows the killer to remain free (whilst ensuring no more women are attacked) so the unsolved murders continue to dominate the headlines. He meets Sookey, an eccentric middle-class slummer and civilising influence. The two of them share a mutual friend, Mary Kelly, a fiery young prostitute whose back-story tells of how she was reduced to such a life.

To fund his surveillance of the killer, Nashey agrees, against his better judgement, to assist an old adversary to commit a daring night robbery under the noses of the huge police presence in the area.

Is it too late for Nashey and Mary to correct their mistakes?
