Arriving in Mumbai with just a backpack and a guitar, Raunaq Kaul hooks up with Surinder Bhan, who introduces him to Charlie, the owner of 'Charlie Tango' nightclub. This is where Raunaq makes his start and achieves phenomenal success as a composer virtually overnight. He quickly regresses to a life of illicit drugs, including Charas, Cocaine, Ganja, smoking, and alcohol. Unable to perform, he goes for a medical check-up with Dr. Manu Rishi Kaul, and is told that he has lost his hearing in the right ear, while the left one is only partly functional. In order to avoid deafness, he must avoid loud music as well as try and keep off drugs, alcohol and smoking, and wear a hearing-aid. Unable to focus on his work, he alienates himself, gets into an argument, which results in an accident - taking away his hearing altogether. Depressed, refusing to communicate with anyone, he prepares a padded sound-proof room with hopes of recovering his hearing...

Wealthy Om Jaiswal has been discharged from a mental asylum after 12 years, lives under the care of Meena Tai, and loves his childhood sweetheart, Jyotika Jhalani. His brother, Abhimanyu, schemes to get him institutionalized but before that could happen both brothers are abducted and held in a locked mall. Together with them are Jyotika, as well as their childhood friends: Jaideep, the son of a politician, Yeshwant Mahajan - who is now a gangster, and uses his goon-power to force non-Maharashtrians to return back to their respective states. Bespectacled and overweight as a teen, Imran Baig, is now a popular Bollywood actor. And Gunita Sodhi - who always had a crush on Om - is now a beauty queen. Neither of them know who abducted them but blame each other - little knowing that soon a mysterious person, wearing a Santa Claus outfit, will soon not only compel them to play a deadly game but will also attempt to resurrect a traumatic and life-changing incident that occurred 12 years ago.
