Sivalinga is Tamil action horror comedy film directed by P. Vasu, starring Raghava Lawrence and Ritika Singh in the leading roles. A remake of Vasu’s earlier 2016 Kannada film of the same name, the project began production in July 2016. The climax revelation scene was reported to have similarities with director’s own 1999 movie Malabar Police. The film received positive reviews and it was a commercial success.
Raheem (“Triggerstar” Shakthi) and his well-trained pigeon Saarah are alone in a coach aboard a train when a blind man enters and reached to an open door. Raheem saves the man, but the man, who is not blind and is a killer turns and throws Raheem off the moving train to his death. Raheem’s death is ruled a suicide, but Raheem’s fiancee Sangeetha (Saara Deva) knows that Raheem had no reason to kill himself. The same night, Raheem appears in Sangeetha’s dream and says that he was murdered. The following day, Raheem’s case is forwarded to the CID at Sangeetha’s request.
Shivalingeshwaran aka Shivalingesh (Raghava Lawrence) is a strict CID officer who is married to a thrill-seeker named Sathya (Ritika Singh). The two live in a house that is near a cemetery. Shiva is assigned Raheem’s case and begins the investigation. The same night, Sathya sees a ghost of a child, and Sathya is frightened by this. However, Shivalingesh cannot see the ghost and thinks that Sathya is imagining it. Then he appoints a servant Pattukunjam (Vadivelu), who is a thief living in that house as a night watchman for the backdoor. The following day, Shivalingesh visits Raheem’s home to investigate Raheem’s relationship with his father and with Sangeetha. Shivalingesh suspects Sangeetha’s father Krishnamoorthy (Radha Ravi) is responsible for Raheem’s death as he disapproved Raheem & Sangeetha’s love.
Sathya’s behavior becomes erratic. She drives around the city while wearing a black dress, she’s redecorated the house with green curtains and lights, and she has cooked Biriyani, even though she has never made the dish before. Later a house servant Pattukunjam and a few other maids tell Shivalingesh about Sathya’s strange behavior. Shivalingesh meets his friend Ashok, who is a psychiatrist. He advises Shivalingesh to observe her behavior secretly. That night, Shivalingesh returns home early. He hears a man’s voice and smells a cigar burning. He heads to Sathya’s room and is shocked to discover that Raheem’s soul has possessed Sathya’s body. Raheem warns Shivalingesh, that he must solve Raheem’s murder.
