The Livingston Gardener (2015)

In order to close the case files on over a dozen disappearances, a persistent detective, a bereaved senator, and a skeptical prison warden agree to the request of convicted serial killer Jim Gardener, granting him a live television interview in exchange for the location of his remaining victims. Facing off against newsman Pierce Lawrence - the investigative journalist that helped bring him to justice - Gardener uses the interview to set into motion a sinister plan that no one sees coming.
