In 1988, post the death of Indira Gandhi and the disastrous operation Blue Star where the army is infamously known to have entered the innermost sanctums of the Golden Temple in Amritsar, the terrorists had slowly begun to regroup in the temple again, this time with more leaders and even larger numbers hiding within the inner sanctum and holding court. The operation undertaken was known across worldwide media as Operation Black Thunder, where the militants were trapped inside the temple and their electricity and food supply was cut off until they surrendered. The man taking up the responsibility was the head of operations of the Intelligence Bureau, Ajit Doval. Posing as an ISI agent, Doval entered the Harminder Sahib and is known to have lived with the enemy for over 2 months.
