Richard Gere leads a tremendous cast in a fascinating and moving exploration of the human mind, based on a remarkable true story.

In 1959, psychiatrist Dr. Alan Stone (Richard Gere) arrives at a mental hospital in Ypsilanti, Michigan armed with the radical belief that schizophrenic patients should be treated not with confinement and electroshock therapy but with empathy and understanding. As his first study, he takes on the particularly challenging case of three men — Joseph (Peter Dinklage, Game Of Thrones), Leon (Walton Goggins, The Hateful Eight), and Clyde (Bradley Whitford, The West Wing) — each of whom believes he is Jesus Christ. Hoping that by getting them together in the same room to confront their delusions he can break through to them, Dr. Stone begins a risky, unprecedented experiment that will push the boundaries of psychiatric medicine and leave everyone involved — including Dr. Stone himself — profoundly changed.
