Revolves around the mysterious death of India's 2nd Prime Minister Shri Lal Bahadur Shastri and attempts to uncover if he had actually died a natural death, or, as alleged, was assassinated.

Lal Bahadur Shastri was the 2nd Prime Minister of India, under whose leadership we defeated Pakistan in 1965. He reached Tashkent, Uzbekistan, after the victory to sign the Tashkent Agreement. It was signed on 10th Jan 1966, after 6 days of negotiations. Shastri died a few hours later. In 1992 a Russian spy from KGB approaches the British Embassy in Latvia. He hands over a briefcase of documents that details the circumstances of how the USSR eliminated state leaders of almost every major country in the world.

Raagini Phule (Shweta Basu Prasad) is an investigative journalist who is under pressure from her boss to produce a "scoop". She gets an anonymous call in which the caller guides her to a set of documents that details Shastri's life and the events leading up to his death. She pitches the idea to her boss that even after 50 years of Shastri's death, his postmortem report is missing, and we don't know whether Shastri died by poisoning or heart attack. The news goes viral.

P. K. R. Natarajan (Naseeruddin Shah) is the home minister of India. Shyam Sunder Tripathi (Mithun Chakraborty) is the leader of the Janshakti party and in opposition. Nataraj tells his close aide that after Nehru's death Desai was next in line to be PM, but Kamraj played kingmaker and installed Shastri as PM and after his death again Kamraj played his cards to install Indira as the PM. Natarajan and Tripathi make a backroom deal to form a committee to investigate the matter with 4 nominees from each side. Tripathi invites Raagini to join the committee. Other members are Justice Kurian Abraham (Vishwa Mohan Badola) ex SC judge. Vivendra Pratap Singh Rana (Prashant Gupta), youth leader. G. K. S. Anantha Suresh (Prakash Belawadi) IAS. NGO worker Indira Joseph Roy (Mandira Bedi), Shastri historian Aiysha Ali Shah (Pallavi Joshi), Director of archives Omkar Kashyap (Rajesh Sharma). Gangaram Jha (Pankaj Tripathi) director of Indian Scientific research council.

Shastri had had 2 heart attacks prior to travelling to Tashkent. At the last minute his stay was changed from a hotel to a Bungalow. The hotel had an operating theatre and an oxygen tank, but the Bungalow had nothing. Doubts are raised about why Shastri was no administered oxygen when he complained of ill health. Also, that total 8 doctors attended to him, but only 6 signed his medical report. Finally, he was given an intramuscular injection, not an intravenous injection which would have delivered the medicine to his heart much faster and would have probably saved his life.

Raagini's secret benefactor gives Raagini the soviet version of Shastri's medical report, which is different to the official Indian version. This report clearly puts a doubt that Shastri's death was not due to heart failure at all. Omkar then reads the book from a former CIA operative that says that since Shastri and Homi Bhabha were very close to acquiring the nuclear bomb, both were eliminated by the CIA. Imran Qureshi (Ankur Rathee) is Natarajan's security chief and was Raagini's former boyfriend. He threatens Raagini to stay away from this investigation.

It then emerges that there were 2 witnesses to Shastri's death, his doctor Chugh and assistant Ramlaal. Both died within a few days of Shastri's death by accidents. No investigation or witnesses. Committee starts forming an opinion that Shastri was eliminated from public memory as he was a greatest reformer in India, and the Congress did not want a non-Nehru to take center-stage in the history of the country. The Green and White revolutions, and the atomic program were all instated by Shastri and yet nobody in India knows about it.

Raagini next turns her attention to Shastri's dead body which had turned black when it arrived in India. This is a clear indication of poisoning. Gangaram brings out the fact that the cook who served Shastri his last meal was a Muslim. He insinuates that the attack on Shastri was carried out by Muslims, perhaps instigated by Pakistan. This infuriates Ayisha.

Raagini manages to meet her Benefactor, who turns out to be an ex-noted editor, Bakshi. Bakshi tells Raagini that after Shastri won the war, it was clear that it would be impossible to remove him from the post of PM and clear the way for Indira. Therefore, the Congress party was implicit with the KGB in eliminating Shastri and installing Indira as PM. Bakshi gives Raagini the Tashkent files and is killed in an accident soon thereafter.

Tripathi and Natarajan take advantage of this and expel Raagini from the committee using the official secrets act as cover. Raagini begs Tripathi to present her evidence to the committee one last time. Tripathi agrees.

Raagini proves that due to the poison administered to Shastri, his body has developed deep cuts and was oozing blood even after death and this is proven by his cap, which he was wearing before his funeral. She got this cap from his nephew, and the cap had blood stains on it. The cuts were because KGB had removed Shastri's organs, so that the poisoning can't be proved. After Shastri's death, India again became is a Soviet colony and the word "Socialism" was embedded in the Indian constitution during the emergency.

Finally, she produces the Tashkent files that were delivered by the KGB agent to the British embassy back in 1992. These files had a chapter on India, the supremacy of the Indian National Congress and the fact that KGB had 300 agents in India, who ran the whole country.

The movie basically implicates that Indira Gandhi was on KGB's payroll and had sold the entire country to the USSR.
