Jagdish (Akshay Kumar) is among a battalion of military officers that comes to Mumbai on vacation. Jagdish is also a secret Defence Intelligence Agent who cannot lie low, much to the irritation of his friend and sub inspector Sathyan. During a bus ride, an attempt to frisk passengers for a lost wallet leads Jagdish to something much bigger. Within minutes, the bus is blown into pieces and Jagdish helps cops nab the carrier of the bomb, who escapes from the hospital only to be caught by Jagdish again. Using tact, Jagdish follows one clue at a time hoping to track down the terrorist on whose orders the sleeper cell terrorists plan to cause mayhem in Mumbai.
