"Ragini MMS" is a 2011 Bollywood Horror film loosely inspired by true events. The story follows a couple who decide to spend a romantic weekend at a secluded house and end up encountering paranormal activities. Though the film is fictional, it is said to have been inspired by a real-life MMS scandal that occurred in India.
