I think Dr. Mishra is the spy and she is the girl who Naveen loved. Rajveer knows that Naveen was prooved a desh drohi because of her but the problem is that he doesn't know her. Now Dr. Mishra is trying to do the same with Rajveer as she knows that Rajveer is here to trace the spy. Huda is her assistant and she is making him do all this so that Rajveer's suspecion is diverted towards him. But Ritu will actually fall in love with Rajveer and at last, we all will get to know that Rajveer already knew that Ritu is the spy and though he'd also fall in love with her by that time, he will shoot her....................
