When a sensational fashion model from the city, Maya Salamon (Ilene Hamann) is found murdered in her apartment, a police inspector, Uday Singh Rathore (Irrfan Khan) is assigned to investigate the case. This leads him to a well-known columnist, Harsh Vardhan (Suhel Seth), who was Maya's mentor and instrumental in her rise to stardom.
