OMG: Oh My God! is a story about a human, Kanji Lalji Mehta who loses his shop in an earthquake. The shop is located in an area in Mumbai, known as chor bazaar. Kanji does not fear God and even puts God on ill usage, for his benefit.
After an earthquake disaster destroys his shop, his insurance claim is rejected and not paid due to act of God clause in the insurance contract. Kanji lodges a claim against God in the court. The notice is sent to all bigger baba's. The judge accepts Kanji's case.
People are outraged at first and resist him but as the case progresses, eventually people side with him. A person who claims to be Bhagwan stays with Kanji eventually helping him. Initially against Kirishna, soon other Gods and their religious leaders become embroiled in the case.
Other people who have lodged complaints with insurance companies for disaster and been turned down also file claims beside Kanji's claim. Soon the case becomes about the false worship and money making business of the sages etc but Kanji is reminded all he has to do is prove with evidence God destroyed his shop with an earthquake. Which he does.
