Louis Theroux: By Reason of Insanity

The series ran 1 season across 2 episodes and has finished, so there is no cliffhanger risk.

Louis immerses himself in the world of Ohio's state psychiatric hospitals, meeting patients who have committed crimes - at times horrifically violent - while in the grip of severe mental illness.
