Plot synopsis:
The film starts with a footballer, Lorry (Prateik Babbar), who gets admission into an American college. Due to insufficient funds, he is unable to fulfill his dream. On the other hand, his girlfriend Tani (Anaitha Nair) got a scholarship to US. Though he is happy for his girlfriend's achievement, he becomes depressed for not fulfilling his own dream. His friend, Ricky (Gulshan Devaiah), tells him that he can get him into the college, but Lorry will have to smuggle drugs along with him. Lorry agrees and at the airport, successfully passes the X-ray machine.
ACP Vishnu Kamath (Abhishek Bachchan) is a previously corrupt cop who had accepted a lot of bribes to satisfy his family. However, his family died in a car accident. Several years later, he is offered a job by the Chief Minister of Goa: to flush out all the drug gangsters in Goa, which he accepts. His success leads to a panic among the drug suppliers. The drug dealers gather for a meeting led by Zoey (Bipasha Basu). Zoey guarantees them that their drugs will be in safe hands if they are given to a mysterious person named Michael Barbosa. Kamath decides to chase Michael Barbosa and finds out about Ricky.
When Kamath reaches Ricky, he is already dead. Kamath finds out about his cocaine-smuggling and his girlfriend, Rozanna (Mariah Pucu Gantois Gomes). They reach the airport on the same day Lorry is about to leave. Kamath encounters Rozanna and finds a photo of Lorry in her phone. She is allowed to go due to lack of evidence. Kamath then identifies Lorry as the person he had seen in Rozanna's phone. They detain him and find cocaine stuffed in his bag. Lorry is sent to juvenile jail, where his friend, DJ Joki Fernandes (Rana Daggubati), tries to get him out. It is then revealed that Zoey and Joki used to date. Zoey wanted to be an air hostess, but failed. Joki introduced her to his boss, Lorsa Biscuita a.k.a. the Biscuit (Aditya Pancholi), who had worldwide contacts. With the help of his contacts, Biscuit got her a job in airlines, though she had to smuggle cocaine to international regions to repay him. She ended up getting caught and was sentenced to 14 years in jail. Biscuit's contact got her free in 14 days, but to repay him, she had to sleep with Biscuit. She broke up with Joki and made her life drug-dealing with Biscuit.
Joki meets Zoey and the two end up sleeping together. Zoey gives him a video of Biscuit announcing that he is going to have a rave in neighboring Karnataka, out of Kamath's jurisdiction and that Michael Barbosa will be bringing and exchanging drugs. Joki gives this tape to Kamath. When Biscuit comes to know about Zoey and Joki, he kills Zoey. After recruiting Lorry for help, Kamath attacks Biscuit's party and arrests the drug dealers. When Kamath's colleague Rane asks him about Barbosa, Kamath says that he knows the secret of Barbosa and Rane kills Kamath. It is revealed that Rane was always involved with Biscuit. Joki later finds out about Kamath's death and arrives at the crime scene, fitting together the pieces as Kamath has. Michael Barbosa is not a man but a gravesite Biscuit uses for storing drugs. We see Joki carefully storing the bags of cocaine somewhere, then calling Rane to arrange a meeting. Lorry is now free of the charge and he comes out of jail. When Joki and Rane are going to meet Biscuit, Joki kills Rane saying that he knows Rane is the person who killed Kamath. Kamath's body is being cremated in an electric furnace owned by Biscuit. We see that this is where Joki has put the drugs, and Biscuit arrives only too late. Having been brought down by the destruction of his stockpile, Biscuit is killed by a woman who may be Rozanna. Lorry comes to a beach party where Joki is singing, and Tani joins him in a joyful reunion. The film ends with Joki riding on his bike envisioning Kamath and Zoey.
