This is the person I am now. It's the person I want to be, should have been for a long time. We got dark, Sophie. Things got dark, and I...I'm better now. I'm in a better place... Once our lives are touched by tragedy, can we ever truly move on? Sophie and Tom's relationship fell apart in the aftermath of a catastrophe. Four years on, as they come face to face once again, the aftershocks of that fateful day can still be felt. Tremor is a play about now. It's about how we choose to see things and live our lives in a world riven with tension, anxiety and division. This thrilling new play by Brad Birch, recipient of the Harold Pinter Commission, offers a taut, intense and thrilling two-hander.
