Bullet: Ek Dhamaka (2005)

India's intelligence services are extremely worried about leaked news of a major terrorist attack on India's Independence Day, January 26th. They task Agents Bobby and Arjun Singh with infiltrating the terrorists operating out of Sofia, Bulgaria's capital. Bobby and Arjun accept the task, but Arjun resigns when he discovers that Don Raja, a Bulgarian businessman who rose to power as a crooked Nasik Police Inspector, is the mastermind behind the terrorist attacks. He decides to go after Don Raja on his own after resigning because he has a personal score to settle with him, and he has a bullet in his gun with Raja's name on it. But the clever Raja is one step ahead of Arjun, and he soon has him trapped in a web of lies and deception, to the point that Arjun is unable to distinguish between terrorists, Indian agents, and ordinary people, and Arjun is soon arrested by Bulgarian police - as a terrorist suspect. It appears that Don Raja will have this way after all.
