The documentary follows the investigation of Sophie Toscan Du Plantier, a French film and TV producer who was killed while at her isolated holiday cottage in West Cork, Ireland, in 1996.
Toscan du Plantier was found by a neighbor at 10 am in a laneway beside her house, dressed in nightwear and boots. Her long-john bottoms were caught on a barbed-wire fence. Bloodstains were on a gate, a nearby piece of slate, and a concrete block. Her body was left outdoors until the arrival of a State Pathologist 28 hours later. He found “laceration and swelling of the brain, fracture of the skull, and multiple blunt head injuries.” The facial injuries were so severe that her neighbor could not formally identify her.
