March 1932. After the recently incarcerated Al Capone offers to negotiate the return of the kidnapped son of Charles Lindbergh, Nathan Heller of the Chicago P.D. is sent to Hopewell, New Jersey, as a police liaison. As a part of Lindbergh's inner circle, Heller investigates crooks, cranks, socialites, and psychics in a frustrating, fruitless attempt to solve the case.
