A mentally unstable artist loses the ability to distinguish reality from dreams after the warring voices in his head become too powerful to ignore, and begin taking human form. His health failing and his rent overdue, John struggles to maintain his sanity by envisioning himself as a diabolical beast roaming the moonlit streets of Seattle in search of victims. Later when John learns to embrace his troubled childhood, he gains the power to confront his murderous inner demon. Will insanity prevail, or will John finally find the inner-peace that's always remained frustratingly out of reach?
