The Bug, one of Earth's greatest heroes has been brutally murdered and his butchered body has been left for the world to see. Detective Marquez has been assigned to investigate, but is forced to drop the case by Captain Power and the other superheroes. They believe that the investigation into the death of one of their own should be conducted by them and is too dangerous for the police. Marquez, however, has sworn to 'serve and protect.' She feels the heroes are out of their depth and therefore must fight against them to protect them.
