On a dark and stormy UK night, BARRY WIGGLE, a sad, pathetic man living with his Mother has locked himself in his bathroom as he battles a squelching bout of painful stomach cramps.

As he tries desperately to convince himself that his stomach issues are just gas, deep down he knows that with every twist, squirm and squelch that his problems stem from one source: THE WUURM.

Somewhere, somehow, poor Barry has picked up a narcissistic, sentient parasite whose only goal is to gaslight Barry, and spend the rest of its life tormenting him from within.

As the WUURM’s voice grows louder in Barry’s head, the more persuasive his words become. With Barry's past week of toilet breaks told in a slew of short, comedic flashback sequences, all that’s left for him to do is expel the parasite and engage in a fast-paced, battle to the death!
