sniper shooter

This movie made me think alot about what's happening around us. I am also guilty for thinking that tanu was the one faking the rape in the first half of the movie. also i didn't understand how nanki decoded tanu being a victim because 1 moment she was in the party of her boyfriend's release and the 2nd mkment she was at the train station with tanu. I hope cn someone explain it. thankyou!!
