6 Alvares House in Bandra, Mumbai, is the residence of myopic, widowed, devout Hindu, Satyabol Shastri, who lives there with his daughter, Shivani. Shivani is in love with her Christian neighbor, Arjun Fernandes, who is a mechanic and lives with his friends, which include Sis, Mohbatti, a wannabe singer, Julie, and a younger, ailing sister, Titli. Satyabol disapproves of Arjun and wants his daughter to marry Sarju Maharaj Banaraswale's son. Other than Satyabol chasing Badshah, the pet dog of Arjun, and ending up in the women's bathroom, the area is fairly peaceful.
Then Arjun and his friends try to think of a plan to stop Sarju from marrying his son to Shivani but can't. So Arjun calls his cousin Kishan to help them. Kishan comes disguised as Sarju Maharaj Banaraswale by tricking the real Sarju into getting off the train, and as soon as he gets off the train, some goons who think he is a relative of Kishan catch him and take him to find out where Kishan is. Meanwhile, Kishan becomes Sarju and convinces Satyabol that his (Sarju's) son is not good for his (Shashtri's) daughter by dancing in the bar and kissing Julie, who was in the act. Then Shashtri informs the fake Sarju that he does not want to marry his daughter to Sarju's son and that he can go now. So having finished his mission, Kishan prepares to leave when Arjun tells him to stay back as he loves Julie, but Kishan refuses to say that he is not destined for Julie. Then, after Arjun leaves and Rana turns up with the real Sarju, but when Kishan says that all the money is with Sarju, they leave. Kishan and run after Sarju while Kishan escapes, disguises himself as a woman named Sunaina, and says 'she' is Arjun's aunty, and soon Shashtri falls in love with her. Then in the neighbourhood also comes Matha Prasad, who runs a dairy farm and moonlights as the hitman of Bangkok-based underworld Don Carlos. The once honest cop Namdev Mane (pronounced as Maa-ne) teams up with Carlos' girlfriend Sania, who is on the lookout for hidden diamonds and facing bankruptcy - Carlos himself - as they face off in one of the most hilarious stand-offs to seek wealth and to fulfill their individual dreams.
