Detective Inspector Rabbit (Matt Berry - Garth Marenghi's Darkplace ) is the top cop at Scotland Yard. He is an old-fashioned kind of copper, who beats confessions out of suspects. Like Gene Hunt, the 1970s thug in Life On Mars , or his more politically correct modern replacement Luthor. However, he is the original version - in the 1870s.
The boss (Alun Armstrong - Krull (1983) ) assigns Rabbit a new partner - a young wet-behind-the-ears rookie. The boss's stroppy adopted daughter Mabel ( Susan Wokoma ) tags along on the investigation.
There is a serial killer on the loose in the East End of London. This not only parodies The Limehouse Golem , but also the modern US TV police procedural genre.
Two of the nastiest gangs in the East End have a deadly rivalry. Detective Inspector Rabbit (Matt Berry - Garth Marenghi's Darkplace ) sends his minions undercover to prevent a gang war.
Detective Inspector Rabbit (Matt Berry - Garth Marenghi's Darkplace ) and his minions go to see a rabble-rouser. His name is Neil Fromage, and he is a rabid xenophobe. Naturally this is a parody of a Little Englander named Nigel Farage, and he gets a violent on-screen death.
The killer is a sniper who taunts the police with notes signed Trigger Tom. His next target is a visiting foreign dignitary, the brother of Princess Juliana of Bulgaria ( Sally Phillips ). She gets upset when her brother is kidnapped.
The sniper's ammunition of choice is also the favourite of Flora ( Jill Halfpenny ), Rabbit's girlfriend. Is she the shooter, or is she being framed?
Detective Inspector Rabbit (Matt Berry - Garth Marenghi's Darkplace ) plans to rescue his girlfriend Flora ( Jill Halfpenny ) from the hangman's noose. It would have been nice if they had given her a trial, but the coincidence of her being in the vicinity of a crime seems enough for them to hang her at noon the next day.
Rabbit and his team get delayed by a different assignment. A man with a cannister of poison gas is holding some match-girls hostage in their factory.
Detective Inspector Rabbit (Matt Berry - Garth Marenghi's Darkplace ) is framed for murder. Tanner (Paul Kaye - Zapped ) tries to arrest him, but Rabbit uses Taika Waititi ( Thor: Ragnarok ) as a hostage.
The villainess monologues our heroes with her evil plan. She will use the electrification scheme, intended to provide better steet lights to the East End, it will drive everyone exposed to the light into a murderous frenzy. Sort of like the villain's plan in Kingsman . The idea is to conduct a slum clearance of the East End, so they can create a matriarchal society. The villains in Brick Man would have cleared the slums with far less loss of life.
Jermaine Clement ( Legion ) pops up at the end, as a messenger boy for Queen Victoria. This is setup for the next Season.
