Three Christs tells the story of an extraordinary experiment that began in 1959 at Michigan's Ypsilanti State Hospital, where Dr. Alan Stone treated three paranoid schizophrenic patients who each believe they are Jesus Christ. Dr. Stone pioneers a simple, yet revolutionary treatment: instead of submitting the patients to electroshock, forced restraints and tranquilizers, he puts them in a room together to confront their delusions. What transpires is a darkly comic, intensely dramatic story about the nature of identity and the power of empathy.
