Prasad, who works as a bus conductor, resides in Tirupathi with his wife Saraswati and their two sons. Arun, the older son, not only struggles in mathematics but also consistently receives a score of zero in all of his exams. A new teacher, Chanakya, demotes the kid from the 6th grade to the 5th grade, resulting in Arun feeling shame and declining to attend school. Finally, Chanakya consents to instruct him on the condition that Arun achieves a score of 35 in mathematics during the final examinations. How will Saraswati, who did not even clear tenth grade and has chosen to be a homemaker, tackle the task of ensuring her son achieves a score of 35 in mathematics?
