Behind Closed Doors examines the mystery behind the double murder of a 13-year-old girl, Aarushi Talwar, and her family's servant, Hemraj Banjade, in their home in Noida, India, which sparked a media frenzy and has haunted an entire nation for more than a decade. The film reconstructs the story, beginning with the early-morning discovery of the murders, charting the initial missteps by local police, the hurried transfer of the case to India's Central Bureau of Investigation, the use of dubious interrogation techniques, the sensational criminal trial and the multiple legal appeals. The documentary explores how class divisions and cultural biases clouded the search for answers, which remain elusive today.
