Causa: The Trial of the Illegal Potato

25 - 26 Sept 2026

Causa: The Trial of the Illegal Potato

An absurdist courtroom comedy audiences have declared: “GUILTY... of being very entertaining.” (Underbelly Boulevard, Belly Scratch 2026).

A Peruvian immigrant faces charges and deportation at a London court for accidentally causing a UK-wide agricultural crisis after growing a bootleg crop of a forbidden potato variety to cook a cherished dish from home to cure her homesickness and appease her cravings.

Under absurd cross-examination and defended by a sub-par barrister, Juana fights to be acquitted, hindered and aided by an odd parade of witnesses: an egotistical restauranteur, a potato-seed-smuggling drug dealer, a pissed-off neighbour, and a catastrophising scientific expert.

As the trial unfolds, questions mount: did her potato cause the crisis or is she just a convenient scapegoat? Should she be deported? Should this new potato, and Juana, be embraced as one of us?

Blending migration politics, ecology, and cultural identity, this is a fast, physical, sharply comic late-night trial where the verdict matters as much as the chaos.
