Upon arrival, he finds out that Chaturvedi's firm has gone bankrupt. He goes job-hunting, ends up having his luggage, wallet, and car stolen by a man named Chali. He locates Chali and forces him to provide accommodation, while he lands himself a job with Malhotra Group of Companies as a lowly Peon. He falls in love with the dress designer, Jasmin Arora, and comes to her assistance as Husn Bano. When he finds out that Malhotra's elder brother, and his associate, M.R. Poplet, are scheming to bring down Mr. Malhotra, he masquerades as David Rathod, an American trouble-shooter.
