You might have seen a poster or a hoarding with an old man with old model spectacles standing alone among the beautiful posters with dazzling and sizzling heroines. He is none other than Rajendra Prasad, who was once a comedy hero and now standing in a serious posture. After getting fame with films like Aa Naluguru and Mee Sreyobhilashi, he has chosen a serious character for latest film Onamalu, which is a beautiful film with a perfect tag-line ‘Manchi Gnapakalamlanti Cinema'.
Narayanarao Master (Rajendra Prasad) is unable to adjust with his children, who were doing jobs in US. Fed up with American culture, he decides to return to his village. The film starts with the flight reaching India. From there he engages a cab to his village and recollects his sweet memories in that village with the cab driver. The entire part before the interval bang is passed on with the recollection alone. In this process, he meets some of his old students on his way. However, he realises how the entire world changed including India with people following western culture and here too people have changed their mentalities including his students. How he makes efforts to enlighten people will form the crux of the film.
