Salman plays an actor who is in the midst of a concert tour. He meets Katrina in the lounge of a Helipad as he is waiting for his flight which has been delayed due to some technical reasons. Kaif proposes to tell a story provided Khan agrees to make a film on it. That’s how she tells the story of the five friends at a Call Centre. Incidentally the film begins and ends with both these characters. In the novel, their interaction was shown on a train but director Agnihotri changed it to Helipad keeping Salman’s larger than life image in mind.
