I went to watch this movie on saturday in carnival cinema & I didn’t enjoyed the story becuase script play could have been better.
Movie starts with Rajat kapur in pakistan as informer for pakustan military in 1975 but was actually working for IB.
Then once he came to know that he is going to die soon due to tumer then he called her daughter Alia bhatt frim delhi university to get trained by IB to work as informer from them as pakistan was planning something big against India.
Then story revolves around alia who was delivering pakistn indormation from military as she was bride of some one big in Pakistan army.
If you wish to go for repetitive script you can opt else avoid.
