Deepak [Govinda], a simpleton, has been switching jobs as he does not want to succumb to the corrupt system. Since years, with unwavering efforts, financial hardships and an unshaken faith in the judicial systems, he has been helping his father [Om Puri] in a legal matter.

His father is fighting a court case against the school to get his due provident fund and pension. He later wins the case and the school is ordered to give a part of its property as compensation, if there is no money in its funds. And thus Deepak's life gets an addition: a bus.

Instead of selling it off, acting on his father's advice, he decides to run the bus, while the rest of the family members -- two sisters Chhaya and Arpana [Upasana Singh and Amita Nangia] and the ghar jamai-husbands [Asrani and Manoj Joshi] -- are against it. Their primary interest is in selling off the house.

Sundar [Rajpal Yadav], who is desperately trying for an American Visa, is also an age-old friend. He comes in handy with initial investments and they establish a company, Chal Chala Chal Transport. And so begins the ride of their lives.
