An Indian narcotics officer concocts an ingenious plan to capture a notorious drug lord, only to discover too little too late just how wrong even the most well-executed plan can go in this Bollywood action thriller from director Farhan Akhtar. As drug trafficking between Asia and Europe rockets to an all-time high, DCP DeSilva vows to bring one of the world's most notorious drug cartels to justice no matter what the cost. Though many believe the powerful operation to be run by the dreaded Singhania, it is actually trusted lieutenant Don who is pulling the strings from behind the scenes. DCP DeSilva knows well that the ruthless and power-mad Don is the true mastermind behind the actions of the cartel, and upon capturing the elusive drug trafficker he sets into motion a complicated plan designed to bring down the elaborately conceived operation once and for all. DeSilva's secret weapon is a man named Vijay. Not only is Vijay the spitting image of Don, but he has studied Don's mannerisms extensively and now possesses the skills needed to infiltrate the group and deceive even the sharp-eyed Singhania. Trouble arises, however, when DeSilva is unexpectedly killed during a raid on the cartel and the only people Vijay can turn to for help are woman who has infiltrated the gang to avenge the death of her brother, and the man who once entrusted Vijay with his son and now owes the frantic undercover cop a sizable favor. But now the ruse has been revealed, and with the police closing in on one side and the vengeful gangsters gaining ground on the other, time is quickly running out for the hunted undercover cop without an identity.
