Psychosis 2023 focuses on Cliff Van Aarle, a criminal fixer haunted by visions and auditory hallucinations due to a unique psychological condition.

He is forced to confront old demons and relive a traumatic past as he battles a sadistic hypnotist and enigmatic drug lord named Joubini, who uses psychedelics and mind control with lethal effect, blurring the lines between reality and nightmare.
