THE MASTER CLEANSE follows Kelly and Scott, a normal couple, who may tell the occasional white lie to keep their relationship afloat. Together they decide to try a fad diet called 'The Master Cleanse' -- a 10 day fast where you only drink a concoction of water, lemon juice, maple syrup, and cayenne pepper. Kelly and Scott thought they were going to clean the toxins out of their bodies, little did they know it would also clean the toxins out of their relationship.
