The series is set in a fading country town that finds itself under siege by an army of murderous garden gnomes on the eve of their first Gnome-a-Palooza festival. At the heart of the story are two police officers, Senior Sergeant Arnold Kipps and his ex-partner from the force (and life) Senior Constable Ellie McKay, who has returned to town with the task of shutting down Arnold’s beloved police station. When the town’s gnome population is brought to life by an ancient evil, all hell breaks loose. Arnold and Ellie must team up with a motley crew of locals to try and save their home from a Gnome-apocalypse.
