Rangasthan is a romantic comedy film with all mass elements. Varun Sandesh and Haripriya's performances and their chemistry are the main attractions in the movie.
Sri (Varun Sandeh) is a shy guy, who is running a company. Attracted by him, a rich girl named Anjali proposes to him, but he rejects her without a second thought. When his company lands in a financial crisis, Anjali's father KK (Ahuti Prasad) comes forward to offer him support, if he agrees to marry his daughter. Sri accepts his proposal and agrees to marry her. In a bid to shed his inhibitions about women, he meets a prostitute named Neeru (Haripriya) and her arrival brings a serious twist in his life. What is that twist? Will he marry Anjali or not? The rest of the movie answers these questions.
