Ishaara (2008)

Professor Khurana develops an injection, "Project X", and administers it to his pregnant wife. She dies in childbirth, but their daughter, Simran Khurana (alias Nisha Oberoi), grows at an accelerated rate. By 10 years old, she is a beautifully developed woman, with an unnatural appetite for sex and murder. Simran overhears her father plot to kill her, and runs away to Goa. There, she stalks and murders several men, leaving behind an "X" in blood on the walls. The police discover her ability to "shape shift", making her apprehension difficult. When her father comes to town, will he be able to identify and nab her before more people are killed?
