Synopsis: 6 Alvarez House in Bandra, Bombay, is the residence of myopic, widowed, devout Hindu, Satyabol Shashtri (Anupam Kher) , who lives there with his daughter, Shivani (Riya Sen). Shivani is in love with her Christian neighbor, Arjun Fernandes (Shreyas Talpade), who works as a Mechanic and lives with his wanna-be singer sister, Julie (Koena Mitra), and a younger ailing sister, Titli. Satyabol disapproves of Arjun and wants his daughter to get married to Sarju Maharaj Banaraswale's son. Other than Satyabol chasing Badshah, the pet dog of Arjun, and ending up in the woman's bathroom, the area is fairly peaceful. But after Sarju hands over a pair of high-heeled shoes to Shivani — a motley group of characters are going to descend on this neighborhood. Chief amongst them being Kishan (Ritesh Deshmukh), the ultimate master of disguise; Nepali Rana Jang Bahadur (Chunky Pandey), who is out to settle old scores with Kishan; Matha Prasad (Rajpal Yadav), who runs a dairy farm and moonlights as the hit-man of Bangkok-based underworld don, Carlos (Jackie Shroff). Arjun's mysterious 'aunt' named Sunaina — who will soon be pursued by a love-lorn Satyabol; the once honest Police Inspector Mane (Suniel Shetty), who along with Carlos' girlfriend, Sania (Celina Jaitley), is on the lookout for hidden diamonds; and last but not the least, facing near bankruptcy, - Carlos himself — as they face/off in one of the most hilarious stand-offs to seek wealth to and fulfill their individual dreams.
One highlight of the film is the number of guises which Ritesh Deshmukh assumes in it. He dresses up as a buxom girl, a Kathak dancer, and a Nepali guard. Celina Jaitley also donned several looks in the film.
