Laxmi Narayan 1 (Tushar Kapoor) lives a poor man's lifestyle in Mumbai with his widowed mother Kanta, who wants him to be a successful gangster and would like him to kill a few people, make enough money, then marry Chota Khujli's daughter, Meena Khujli. To fulfill his mother's wish, Laxminarayan #1 accepts a contract to kill D'Mello Yadav (Mukesh Tiwari), a Pondi-based gangster, who has stolen a diamond.

Laxmi Narayan 2 (Sunil Shetty), the detailed and obedient Secretary of D.M. Pipat, wants him to buy a vintage car from a Pondi-based used car dealer, Laila (Sameera Reddy). Laxmi Narayan 3 (Paresh Rawal) sells undergarments and runs a business, 'Bulbul Lingerie,' with his son, Sonu; he travels to Pondi to meet with his new supplier, Jiya (Esha Deol).
