Sarah, the wife of a theater director, decides to leave her mutt of a husband because she is tired of his morbid fantasies. It is true that Baptiste has a rather unstable troupe that rehearses horror plays in a dance hall. Sarah comes out of the wings for life, but it turns out to be as incongruous and phantasmagorical as her husband's plays. This is why she returns to him. "The real grand guignol is life. The other is the farce."
Unfortunately the movie Grand Guignol is not yet available on HBO Max.
