Themroc, a bachelor house painter living at home with his mother, leads a sad and colorless life. One day, after a run-in with his boss, he rebels. He wrecks his apartment, rejects every facet of bourgeois life, and begins acting like an urban, modern-day Neanderthal.

Known for his suave, bourgeois characters, Michel Piccoli underwent a brutish and animalistic transformation in Claude Faraldo’s provocative cult film, which dispenses entirely with dialogue. Comprising grunts and gestures, Themroc is an antiestablishment battle cry against society’s conformism.
