Mission 90 Days is a 2007 Indian Malayalam-language film directed by retired Army officer and former commando Major AK Raveendran SM starring Mammooty.

The government of India constituted SIT a day later, and Major Sivaram a top investigation officer and a NSG commando with a proven track record is put in charge to hunt down the killers.

Sivaram due to his meticulous and systematic search is able to piece together the case, after the arrest of Murugan, Nalini, and their interrogation leads the team to the conspirator Sivarasan hiding in a house in Bangalore.

Major Sivaram, waits the entire night for the order to start the operation, which is given only next day after the bosses arrive, at 10am in broad daylight in front of thousands of onlookers and bungling Karnataka police.

The surprise element in the operation is lost as Sivaram finds to his horror the entire LTTE team had bitten the cyanide and Sivarasan the kingpin had shot himself, a few seconds before they broke in.
