Detective Terry Todd is missing and presumed dead. His daughter, Detective Terri Todd, new to the police force, has vowed to find out what happened to him. When a mad scientist brings Todd back to life, combining him with the bodies and spirits of three notorious dead gangsters, and calls her new creation "Frankie", all hell breaks out in a town already at the boiling point with warring gangs and the hapless monsters that live under the crime and corruption that plague the metropolis. As the inhabitants of Monstros City, the vampires, werewolves, goblins, and "exceptionals" fight for their survival under the boot heels of the mob and corrupt city officials, Frankie and Terri, father and daughter, eventually find each other, and fight to make Monstros City safe for all.
