1903. In the back streets of Montmartre, the Theatre du Grand Guignol opens its doors to an unsuspecting public. The plays performed, rife with madness and murder, are sold out every night. A psychiatrist obsessed with the playwright's gruesome dramas ingratiates his way into the company. But when he starts to unpick the author's mind, the boundaries between theatre and truth begin to blur. Delighting in this lost theatrical form, Carl Grose's demented new play works fast and loose with convention. A black comedy, a psychological thriller and an unrepentant splatterfest, Grand Guignol is a head-spinning, genre-bending phantasmagoria guaranteed to keep you guessing (and wincing) to the very last horror show.
