 Reshma ( Vidya Balan ) is running away from her house to Chennai , a day before her marriage . She is insulted by the casting director for being unattractive and useless after trying to get a role in a film . Determined to convince him she spontaneously grabs the role of a side dancer . However , she dances with whips and using erotic movements which annoys the film 's director , Abraham ( Emraan Hashmi ) . He edits out Reshma 's entire dance sequence from the film . The film fails at the box office much to the dismay of the producer Selva Ganesh ( Rajesh Sharma ) , who later offers Reshma a song in his upcoming film , and suggests that she now be referred to as " Silk " .
