Oliver Stone once said, "One of the joys of going to the movies was that it was trashy, and we should never lose that." The reason for giving that quote is not just to fill up the number of lines (of course, that is a bonus!), but that you might need to keep remembering it while watching this movie.
Donga Sachinollu is about two imbecile brothers – Ramudu (Raghu Babu) and Kamudu (Krishna Bhagwan). They live in a village with their uncle and aunt (Chandra Mohan and Telangana Sakuntala), and happen to be bachelors -- not by choice, but because no one is willing to marry them.
