Building on Maher's theory that religion is a neurological disorder, RELIGULOUS attempts to chart similarities and differences of a wide range of modern religions. In order to test his hypothesis, Maher meets with Jews for Jesus, Muslims, polygamists, Satanists, Hasidic scholars and even Rael, the founder and leader of the Raelian Movement.
