I'm Kartar Singh, Sub Inspector in Mumbai Police.
I think my life is unambitious because I haven't done anything which can be acknowledged. I have only one reason to smile in the world, my sister - Avneet. I had resigned from the Police force. On the other end, Avneet has found the main suspect in a mysterious murder case with uncountable and folded twists.
Here I present, most thrilling days of my life.
