William (Will) Pinkerton has been assigned to investigate a series of bank robberies in and around booming Kansas City. When thieves rob a train (the first time a train has been robbed!) and kill a Union Army sharpshooter on his way home from the just-ended Civil War, it becomes clear there is more going on here than meets the eye. Allan Pinkerton calls in his best agent, Kate Warne, to take over his son’s investigation. Initially appalled by the idea of working for a woman, Will soon finds Kate to be smart, resourceful and brave. Not to mention attractive.
