Based on Jean-Xavier de Lestrade’s true-crime docuseries and various books and reports on the case, the limited series explores the life of Michael Peterson, his sprawling North Carolina family, and the suspicious death of his wife, Kathleen Peterson. In 2001, Peterson was arrested for the murder of his second wife after he had claimed that she died after falling down the stairs at their home due to consuming alcohol and Valium. However, the autopsy report refutes Peterson’s claims because it concluded that she died from sustaining multiple injuries, including blows to the back of her head with a blunt object.

Binoche’s character is currently unknown, with Deadline reporting that it’s being kept under wraps for the time being. However, the star-studded cast continues to grow, and it looks as if HBO is hoping this will another in a long line of hit dramas that reach massive levels of success.
