After holding onto heartbreak for several years, Paul decides to restart his life, joining a spiritual retreat designed to cleanse negative toxins from his body.
But things take a turn when Paul and the other participants discover that the cleanse releases something far greater than everyday toxins and traumatic experiences. A soulful and humorous blend of Cronenberg body-horror and old-school Amblin, THE MASTER CLEANSE asks the all-important question: can we kill our demons before they kill us?
