A man falls from a third-floor window at a snowed-in mountain chalet. His wife, a successful novelist, is charged with his murder. Their 11-year-old visually impaired son becomes the only witness. The trial unfolds over a year, and we watch a marriage be litigated in public — every fight, every infidelity, every page of her fiction that might be evidence. Triet refuses to tell us whether Sandra did it.
