Kanji Lalji Mehta (Paresh Rawal), a middle-class atheist Hindu owns a shop of Hindu idols and antiques in Chor Bazaar, Mumbai. He is cursed by Siddheshwar Maharaj when he stopped his son from playing dahi handi. A low-intensity earthquake hits the city, and Kanji''s shop is the only shop that is destroyed. Next day at the insurance office, Kanji and his neighbour-assistant Mahadev learn that the disaster claim does not cover any damage caused by natural calamities classified under ''Act of God''. Running out of options, Kanji decides to file a lawsuit against God.
