Renowned psychiatrist Sam Allyn has fallen from grace, landing at a remote institution specializing in the Jerusalem syndrome, the sudden belief that one is a living, breathing figure from the Bible. There he confronts Patient X, whose behavior is so volatile, so mysterious, so infectious that Sam begins to question whether she is really suffering from psychosis or from something far more terrifying– something not to be cured but destroyed. The Coming is a psychological thriller that pits good vs. evil, sanity vs. insanity, and has us questioning which one is which.
