This masterfully crafted biography illumines the mysterious life of Shirdi Sai (Nagarjuna), who appears in Shirdi at an early age and disappears. He goes to the Himalayas and returns to Shirdi after a gap of 9 years.
He chooses a dilapidated mosque as his abode. Amazed by his presence and miracles, the local people start calling his Sai and Baba. He keeps helping people around and spreading communal harmony by saying that there is only one God.
Certain local people are suspicious of Sai Baba and they learn about his greatness over a period of time. The rest of the story is all about what Sai Baba did to make Shirdi the only pilgrimage for people of all religions and about he entering Samadhi.
