A taxi driver and the son of a rich businessman come in contact with each other. The taxi driver, ashamed of his profession, lets everyone think he is an insurance broker while the rich youngster has to retrieve his father's will and eventually leaves the locker key in the taxi driver's cab in an accident. The driver gets falsely accused and is put in jail while the rest of his family comes to know his true job as a taxi driver. The debacles that occur thereafter form the crux of the story.
