The US Supreme Court's Citizens United decision opened the floodgates to unlimited "dark money" contributions from undisclosed sources to political action committees. Citizens Ununited tells the story of a super PAC that uses its contributions for sinister purposes until heroine Alexandra (Alex) Pipe ends their ploy. Alex, a former Montana rodeo star and sharpshooter now living in the Boston area, finds suspicious data hidden in computer files while working for a defense contractor. During her investigation, she learns that political contributions are used to buy military weapons through shell corporations. But for whom are the weapons being purchased? Terrorists? The Russians? Alex and a rogue FBI agent are chased across the county by the super PAC. Several gun battles ensue where Alex's shooting saves their lives. The trail of evidence leads them to an abandoned Montana missile site where they learn of an impending overthrow of the US government.
