The Outsiders, newly located to Los Angeles without The Batman and embracing newcomer Looker, have to guard the grand opening of a nuclear power plant that has been targeted by terrorists. Little do they realize how unusual these "terrorists" are when they encounter The Nuclear Family ... Mom, Dad, Biff, Brat, Sis, and Dog! After fighting them, the Outsiders decide to use Looker as a decoy to find out who is behind the Family, but she is soon captured by their creator, radiation-sickness stricken Doctor Eric Shanner. He plans on destroying all life on Earth with radiation sickness as well!
