Regulators: Hell On Earth Part One is basically the story of nine uniquely gifted vigilantes who one by one appear to claim justice where there is none by extracting a very harsh penalty. They join forces when it becomes obvious that they have a common goal. Then a monster called Helloween Jack appears and invites the people of the Earth to a Halloween Party that will end with the end of all mankind unless nine vigilantes, The Regulators, can stop him
