by Simon Stephens

(playwright of 'The Curious Incident of the Dog in the Night-Time')

directed by Matt Pfeiffer

FEBRUARY 7 - 25, 2018

REGIONAL PREMIERE! Amidst the bustle of a crowded London train station, Georgie spots Alex, a much older man, and she plants a kiss on his neck. This electric encounter thrusts these two strangers into a fascinating and life-changing game. Heisenberg brings to blazing, theatrical life the uncertain and often comical sparring match that is human connection.


Due to sexual situations and profanity, the show is best suited for mature older teens and adults.
