Give some stream of consciousness and then the answer. The story revolves around Arjun (Emraan Hashmi), a street-smart young conman with an obsession for making a quick buck. He has a chance meeting with a girl at a mall and falls in love at first sight. Zoya was gazing at a ring placed inside showcase protected by glass and hoping to acquire this ring. He breaks the glass to grab the ring she was looking at, that leads him to be caught by the security guards patrolling in the mall. He is arrested and handed over to the police. Inspector Ajay (Sameer Kochhar) is amused but lets him go with a warning as he knows Arjun's father. Zoya (Sonal Chauhan) gives him the reasons he was looking for to move out of his ordinary life and become rich for this girl. He steps up from playing small-time card games to becoming a bookie and strikes gold.
