[5] Dr. Alan Stone, a progressive and idealistic psychologist, dropped out of New York University in 1954 to work directly with patients at the Ypsilanti State Mental Asylum.

In Ypsilanti, Stone meets two patients who both believe they are Jesus Christ: the short intellectual Joseph Cassell and the gruff Clyde Benson.

He has another patient transferred to Ypsilanti who also believes he is Christ, Leon Gabor, and brings the three men together to study their behavior.

Gabor suffered all his life from his deeply religious mother, and he was also traumatized by multiple rapes by a man he had been exposed to as a soldier.

Contrary to the skepticism of many colleagues, including the head of the institution, Dr. Orbus, Stone takes a different course and, for example, completely dispenses with physical punishment.

When he makes the cover of a professional journal with his new approach, it arouses the envy of Dr. Orbus, who wants a share of the fame and henceforth urges to be involved in the treatment.

Since Stone reacts reservedly to Orbus's obvious craving for prestige, the latter finally bypasses the colleague and lets Cassell be taken alone to his office for an interview.

It is revealed that Stone wrote the letters to Cassell on Orbus' behalf since the head of the asylum originally declined the task.

The website's critics consensus reads, "Three Christs is far from an unholy mess, but this fact-based drama forsakes its talented cast with a disappointingly facile treatment of genuinely interesting themes.
