Late at night on a deserted road, well-known actor Armaan Kapoor (Vivan Bhatena) loses control of his car, apparently trying to avoid something, and drives into the sea. Senior Police Inspector Surjan Singh Shekhawat (Aamir Khan) with his assistant Devrath Kulkarni (Rajkummar Rao) begins an investigation. Surjan’s personal life has been in turmoil ever since his 8-year-old son, Karan, recently drowned during a family outing. His wife, Roshni (Rani Mukerji) is still grieving and Surjan has developed a guilt complex.
Surjan learns that on the night of Armaan’s accident, Armaan was travelling with ₹2 million in cash, which is missing. Armaan had given the money to a blackmailer, a pimp named Shashi (Subrat Dutta). Three years back, Shashi had performed a cover-up for Armaan and his friend Sanjay (Suhaas Ahuja). Once he learns of Armaan’s death, Shashi takes off with the cash. Shashi’s friend, Tehmur (Nawazuddin Siddiqui), begins blackmailing Sanjay. Sanjay has Shashi murdered.
Roshni seeks solace from a medium neighbour, Frenny (Shernaz Patel), who is in touch with Karan’s soul. One night, Surjan is propositioned by an escort, Rosie (Kareena Kapoor). He declines but asks if she can become an informer. The police find Shashi’s body, along with the blackmail money and a DVD. The DVD contains embarrassing CCTV footage of Armaan and his friends leaving a hotel with a girl. Rosie confides in Surjan that three years ago, she was picked up by Armaan and his friends, Sanjay and Nikhil, but reveals nothing more. Surjan discovers that Nikhil has been brain-dead after the incident three years ago.
Sanjay has Tehmur killed next. The police learn he is behind Shashi and Tehmur’s murders and Surjan arrests Sanjay. Sanjay confesses that three years ago, he, Armaan, and Nikhil had picked up an escort to celebrate Nikhil’s birthday. Nikhil began making out with the girl in the backseat. The car door opened by accident, throwing both Nikhil and the girl from the moving car to the road. Armaan and Sanjay rushed Nikhil to the hospital but fearing scandal, left the girl on the road. Sanjay had called Shashi to take care of her. Shashi informed them that the girl had died and that he had footage of the three leaving with her. Since then, Shashi had continued to blackmail them for money. Surjan re-watches the footage and realizes that the girl is Rosie.
As he drives Sanjay to the police station, they approach the same road where Armaan had his car accident. Both men see Rosie standing ahead. In a re-enactment of Armaan’s accident, they swerve the car to avoid a collision with her and it falls into the sea. With Sanjay already dead, Surjan struggles to get out of the car. Rosie saves him. Surjan’s superior advises him against reporting the incredible story and Surjan writes in the official report that Armaan’s death was an accident. He returns to the riverside place where he used to meet Rosie and uncovers her remains where Shashi had hidden her body. Remembering that he had been told that “the dead come to those who are troubled,” he gives her a proper funeral.
Now more accepting of the supernatural, Surjan finds a letter from Karan, penned by the medium. Through the letter, Karan tells Surjan not to blame himself for his death and that he wants both his parents to be happy. Surjan cries and reconciles with his wife. In a post-credits scene, two workers are seen putting a caution signboard on the same accident spot.
