A mother and son inhabit an isolated and increasingly dangerous private world.

The third and final installment of Ariana Harwicz's "Involuntary Trilogy" finds us on familiar, disquieting ground. Under the spell of a mother's madness, the French countryside transforms into a dreamscape of interconnected imagery: animals, desire, the functions of the body. Most troublingly: the comfort of a teenage son. Scorning the bourgeois mores and conventionality of their small town, she withdraws him from school and the two embark on ever more antisocial and dangerous behavior. Harwicz is at her best here, building an interior world so robust, and so grotesque, that it eclipses our shared reality. Savage, and savagely funny, she leaves us singed, if not scorched.
