Thalapathi

Surya (Rajinikanth), the abandoned child of fourteen-year-old unwed mother Kalyani (Srividya) is brought up by a generous lady living in the slums. He grows up to become a hot tempered youth who fights the injustice that takes place daily. These qualities lead him to cross swords with the local don Devarajan (Deva) (Mammootty). Devas friend Ramana is fatally beaten up by Surya, and Deva threatens that if his friend was laid to rest then he will kill Surya. Ramana succumbs to his wounds, and Surya is imprisoned.

However, when Deva discovers Ramanas offence, he decides to get Surya released from jail.Surya is surprised to see Deva send his man to get him out from jail, and there he tells Surya, Nyayamnu onnu irrukku (there is such a thing called justice). From that moment, Deva surrenders his ego and offers his hand of friendship to Surya. Surya pledges that he has nothing else but his life to give his new friend. From then on Deva makes Surya his Thalapathi (commander).

Meanwhile Surya falls for a local girl Subbulakshmi (Shobana). They soon fall in love and their relationship continues. Surya and Deva virtually rule the town with their muscle and their sense of justice, but in the eyes of the government they are anti-social elements. Arjun (Arvind Swamy), posted as the new district collector, plans to arrest both so that he can end their brutal activities. But his opportunities are futile.

At this time, Deva and his wife go to Subbulakshmis house asking for her betrothal to Surya. But her father refuses stating he cannot marry his daughter to a person who doesnt know about his parents. Instead, Subbulakshmi is married to Arjun. Surya eventually marries another girl (Bhanupriya) who was widowed by him earlier (her husband was Ramana). Surya, still troubled by the guilt, prefers to remain as a guard to the widow and her daughter.

A struggle breaks out between the collector and Deva/Surya during which Surya learns that Arjuns mother is his mother, too. Surya promises his mother that he will not harm Arjun but refuses to leave Deva, whose friendship is more valuable to him than any other relationship. Deva is stunned to learn that collector and Surya are brothers and admires Surya for not parting with him in spite of discovering his identity. During the process of surrendering to the collector, assuring him completely stopping their activities, Deva is shot to death by his enemy. Surya, in a fit of rage, brutally kills Kalivardhan (Amrish Puri) who was the cause for Devas death and surrenders to the police after performing the final rites of his friend.

But the police withdraw the case due to lack of evidence and witnesses. The collector goes to another place on a new posting accompanied by his wife. His mother then changes her mind to stay with her elder son, Surya.
