Boss Engira Baskaran

In Kumbakonam, the cheerful Boss runs into Chandrika during an arrear examination. He is instantly drawn to her, even though she disapproves of his attempt to copy. This moment sets the spark for their complicated relationship.

Boss learns that Chandrika is the younger sister of his sister-in-law Nandhini after Saravanan marries Nandhini. The revelation complicates his pursuit, since family ties influence his path to marriage. The unfolding dynamic drives him to prove himself more than ever.

Unemployment among his family is repeatedly cited as the reason he must prove himself. Boss resolves to win Chandrika and a future by showing he can stand on his own. He leaves home in search of a path to success.

Boss endures several obstacles and is insulted by Shanmugasundaram, who represents the social pressure against him. He also loses his shelter, making his struggle very personal. The hardships underline his determination to change his fate.

With Nallathambi's support, Boss launches a tutorial centre to help Class X students. The venture gradually becomes profitable as the students begin to top examinations in the state. This marks Boss's first major step toward financial independence.

Velpandi, a local don, signs an agreement that if his son Paalpandi fails the examination, Nallathambi will lose his property and be forced to work in Velpandi's cow-dung place. The threat underscores the leverage Velpandi holds over the system. The deal foreshadows the high-stakes environment Boss is navigating.

Velpandi explains his family history of manipulation in exams and Paalpandi's bizarre sleeping in the examination hall; waking him would provoke a bite. Over time, Paalpandi begins to listen as Boss assigns a blind teacher, and his study method changes. The tutoring center becomes a catalyst for real learning.

Paalpandi eventually studies and passes the examination with favourable marks, causing Velpandi to tear up the original agreement. Velpandi also offers Nallathambi a large, no-interest sum and praises him. Chandrika's love in return for this turn of events becomes more certain.

Shanmugasundaram opposes Boss and Chandrika's marriage, claiming revenge for Boss's earlier failure to obtain a loan. The opposition adds tension and makes their union seem unlikely. Boss and Chandrika's commitment remains tested by this gatekeeper of tradition.

Shiva, a seemingly teetotaler and son of a businessman, is introduced as Chandrika's prospective groom. Boss reveals his love for Chandrika, and a confrontation with Shiva ensues, threatening the couple's future. The clash is later revealed as a staged drama orchestrated by Nallathambi.

When Shanmugasundaram confronts them, it becomes clear that the fight was a ruse. Shiva and Boss team up, and Shanmugasundaram returns to the fold, realizing the manipulations. Nallathambi uses the ruse to unite Boss and Chandrika with renewed resolve.

Under the guidance of Shiva and Boss, Shanmugasundaram relents and unites Boss and Chandrika. M. Rajesh even instructed Shiva to end the quarrel and bring the couple together. The story ends with the couple's union and the triumph over obstacles.
