Venkat succeeds on his theory and submits his report to the institute where he teaches, but they reject his report. Venkat is sure about his theory and wants to try out in reality with live players. So he talks with younger professor Shantanu R. Madhavan about his theory and tells him to get three students to try out this experiment. Shantanu arranges three students Sid Siddharth Kher, the college rockstar Aparna or Apu Shraddha Kapoor, the studious geek, who has a crush on Sid and Vikram or Vikku Dhruv Ganesh, the boy next door. They come together and start playing the game. Venkats theory, like the last time, proves to be successful. Venkat says that after a few more games hell be sure to crack his equation and even be able to study it better. Shantanu tells him that he should try using his theory in the real world, where there are people who actually gamble and play Teen Patti, i.e. in underground dens or addas.Although Venkat has no interest in the money that could come from practicing his equation to crack Teen Patti, he eventually succumbs to Shantanus charismatic persuasion. Soon, with the help of his new students, they explore the addas of wild Bombay. Later another student from the institute, Abbas Vaibhav Talwar, the rich spoiled brat joins the gang and arranges for them parties in casinos, private clubs, etc. But what starts out as an experiment between a charismatic young professor and an eccentric older one soon descends into a game neither of them can control. The money they earn gets stolen someone is blackmailing them they get greedy about money and, in the course of time, they change into different people and even start betraying each other. ........
