The series is set in Victorian England and follows the exploits of a 13-year-old undertaker named Ulysses Jonathan Grimsby, who secretly doubles as the biggest hitman in all of London, and his gravedigger companion Fritz, who is secretly a "homunculus", which in the series is a creature similar to that of the Frankenstein monster.

Plot
Set in England in the year 1888, Ulysses Grimsby is a 13 (later 14)-year-old boy whose family are the owners and operators of the Grimsby Cemetary and Funeral Parlour. Following their deaths supposedly by a highwayman, Ulysses inherits their business despite his age. Ulysses is also informed of and inherits his parents' hitman empire, with many flocking to his parlour to request him to murder ("bury") their enemies, all of whom end up buried in the cemetary which Ulysses owns. However, Ulysses has made a rule for himself to only accept missions ("undertakings") where he deems the victim as deserving of death. Along the way, Ulysses is accompanied by the homunculus Fritz, who is immensely powerful and is currently working as a gravedigger in the cemetary, Ulysses having found Fritz mysteriously buried in the cemetary. Along the way, the pair combine Ulysses' genius with Fritz's strength to combat murderers, thieves, conmen, rapists, and so on, all of whom end up buried in their graveyard.
