The Devil you know isn't always better. When a U.S. Senator's son turns up dead in New York, a Russian ambassador is suspected of murder. But with diplomatic immunity, the U.S. has no recourse - at least no legal recourse. Led by Brady Hawk and Alex Duncan, the former Firestorm team is reunited to help track down a killer and get justice. But they find a dark secret and a far-reaching conspiracy that not only endangers their own lives but also the lives of millions. Hawk and Alex enter a high-stakes race to stop a potential disaster and gain justice outside the confines of the law.
