Ragini MMS is a 2011 Indian found-footage horror film directed by Pawan Kripalani and produced by Jeetendra and Shobha Kapoor of Balaji Telefilms. It was released on 13 May 2011 (Friday the 13th). The film is inspired by the 2007 American supernatural horror film Paranormal Activity and is partly based on the real story of a girl from Delhi named Deepika.

The whole film is shot as a homemade movie, starting with Uday arriving at Ragini's home. After asking Uday where they are heading and getting no response, Ragini's friend, Pia, gets upset and wants Uday to leave their house immediately. Uday pays no heed to her, wakes Ragini up from her sleep, and tells her to get ready for their weekend getaway. They then travel to Uday's 'house' – a mysterious abandoned building at a deserted location. Ragini's mom calls her to ask her whereabouts, but Ragini lies and hangs up.

It is revealed that Uday is involved in the business of making and selling sex tapes of innocent girls. This time the victim is Ragini, who thinks that he loves her. They try to have sex, but are interrupted by Pia and her boyfriend Vishal visiting them. Furious by their visit, Uday tells Ragini to get rid of them, but they end up staying for a while.

Vishal asks Uday for the way to the bathroom and Uday tells him. Vishal tells Uday that a woman previously lived in the house, who was called a witch by her family. The family killed her, following which her spirit murdered them and has since been haunting the house. Uday laughs at this story and walks away. Vishal hesitantly makes his way back to the living room but senses someone behind him.

Someone knocks on the main door. When Uday opens, Vishal stumbles in with a wound on his neck. Sensing that something is wrong with the house, Pia and Vishal leave in a hurry. Afterwards, Uday turns on the cameras without informing Ragini and handcuffs her to the bed. They are about to have sex but Uday is pulled away by his hair. He checks the whole house, during which the door which Vishal had gone through opens inexplicably.

Now afraid, Uday checks the room and house thoroughly but finds no one. They hear some strange sounds and Uday says in Marathi, "I am not a witch." He again goes out to check the source of the noise. He returns in a strange and frightened condition. Ragini immediately asks Uday to release her, but he is scared and unable to think. While searching for the keys, Uday accidentally reveals the camera he was using to film them having sex, to which Ragini reacts with terror, shock and anger.

Uday tries to unlock Ragini's handcuffs with other items but suddenly he becomes paranoid. He picks up a pointed object, stabs himself in the neck, and dies. Terrified, Ragini screams for help but no one hears her. She tries to search for the keys herself, but in vain. She tries to break the bed post, but fails. Ragini finds a piece of glass, cuts her hand, and uses the blood as a lubricant to break free.

Once free, she tries to escape from the house, but the doors keep closing on her. She screams for help, alerting some passersby, who are however unable to help. Ragini is pulled into the same closet where she finds a dead body. She makes a run for the car. She breaks open the car's window and pulls Vishal's body out, but is unable to start the car. She again runs through the jungle and hides in a spot where she finds Pia's body. Eventually the spirit pulls her by her hair back into the house.
