After Assistant Commissioner Agnel Wilson (Randeep Hooda) unsuccessfully attempts suicide, he recounts his story of the Mumbai, India, underworld, which he'd been investigating for decades. It begins with the tale of Sultan Mirza (Ajay Devgn), a smuggler. Wilson attempts to take Sultan down through the gang leader's relationship with a Bollywood actress, but his attempt fails. Then a rising gangster, Shoaib Khan (Emraan Hashmi), overthrows Sultan -- but the power struggle is far from over.
