The Pinkertons: no one saw them coming.
Drawing on the archives of the Pinkertons National Detective Agency, each hour-long episode follows the Pinkertons as they use a mix of the technology of the time, undercover work, and plain old fisticuffs to get their man – or woman.
The first season of the series begins with Allan Pinkerton’s arrival in Kansas City. His son William is struggling to solve a case that has just escalated to train robbery and murder. To William’s consternation, Allan brings in his best agent, Kate Warne. Kate reveals herself to be clever, methodical, and a direct contrast to William’s intuitive approach to solving crime. Neither William nor Kate are happy with their forced partnership, until William’s bravery saves Kate’s life, and Kate’s cunning forensic work helps crack the case.
Allan leaves the unlikely pair in Kansas City where they take on a rogue’s gallery of criminals of the time such as Jesse James and Belle Star. Despite their tumultuous relationship, a warm friendship and surprising chemistry develops between Kate and William.
