A field. A gang. A gun. A frightened boy. His brave sister. Their determined mother. And a towering steel obelisk overseeing it all. 'Pylon' is about fractious family relationships, the horrors siblings subject each other to and the indelible marks they leave.

The story unfolds over the course of a day in a surreal East London. Rat King, an eccentric and unusual pest controller, and his trusting and enthusiastic apprentice River drive a van from one place to another in the city, carrying out their daily work.
