Tamasha is about the journey of someone who has lost his edge in trying to follow acceptable conventions of society. The film is based on the central theme of abrasion and loss of self that happens in an attempt to find oneself.
All stories are same and yet one needs to find their own story. But before you start the journey of creating your own story, one must free oneself from being a character in stories created by other people. Ved (Ranbir Kapoor) is one such character displaying erratic behavior who realizes that the end to his suffering is to create his own story.
Ved and Tara accidentally meet in Corsica, France and decide to spend the next 7 days together with secretly revealing their true identity or without any promise to meet later, ever. Tara eventually falls in love with Ved and goes to find Ved after 4 years, and helps him to find his true story where he belongs.
