Deven Yuvvraaj (Salman Khan) is a struggling singer who signs an agreement with his girlfriend Anoushka’s (Katrina Kaif) father Dr. Banton (Boman Irani) to be a billionaire in 40 days.  To acquire this wealth, he has to go through an emotional roller coaster journey of joy and pain with his two estranged brothers Gyanesh Yuvvraaj (Anil Kapoor) and Danny Yuvvraaj (Zayed Khan) who he meets after 12 years. On meeting them, he realizes that they are two individuals who are completely opposite to each other, which makes his task all the more difficult.
