UK Premiere
A Glass Mask Theatre Production

A Slow Fire

BY SIMON STEPHENS

DIRECTED BY REX RYAN.

20 August -
26 September 2026

Overview

“The hope is what matters”.

Years after the apocalypse, Ashton and Reece survive in a bunker on the edge of an imaginary city. Searching for hope, they spend their days acting out stories from the before times. When a stranger appears, is he here to save them? Or is he telling a tale too good to be true?

The staggering new play from Tony and Olivier award winning Simon Stephens is part thriller, part excavation of the soul. Rex Ryan directs this UK premiere.
