If the latest buzz is to be believed than Kareena plays a Pakistan-based CIA agent, who works for a group of money-grubbing, astute businessmen, who want to make humungous profits from a war-like situation in Asian subcontinent. While Bebo's character has shades of grey with altogether five different looks, than beau Saif Ali Khan is essaying the title role. She will be wearing different looks with prosthetics, quite similar to Hrithik's guises in DHOOM 2.
It must be recalled that Kareena has played a baddie earlier also in the film FIDA, which starred her then boyfriend Shahid Kapoor. However, the film couldn't gain the expected results. Hope this time Kareena's negative avatar does some magic!
