The series was created by Charlie Aspinwall and Daley Pearson, best known for their work on Bluey, and is a co-production between Ludo Studio and Media World Production.

The show centres around two teenage warrior-heroes (Charlie And Pierce) and a spirited ghost girl (Que) who master the skills they need to replace an ageing monster-slayer by doing his supernatural chores.

[5] Two teenagers, Charlie and Pierce, discover that their "kooky neighbour" Old Man Helsing's house at the end of their street is secretly a portal to supernatural worlds.

A mischievous ghost girl, Que, joins them on their adventures as they complete Helsing's freaky, bizarre, and sometimes terrifying chores.

Ludo aimed for an older audience for this show (8 to 12-years-old) when compared to their massively popular preschool series Bluey.
