Gopalam, the zamindar of Appapuram, is the principal of a high school named after his elder daughter Mahalakshmi. As a child, she went missing during a pilgrimage in Kakinada. Conditions at the school deteriorate due to mismanagement by Gopalam's nephew A. K. Raju, an amateur detective. This is exacerbated when Panthulu, an ayurvedic doctor, teaches the children. Gopalam decides to replace them with a male and a female graduate (preferably a married couple) capable of training his younger daughter Sita in singing besides teaching children at the school.
