Fourteen-year-old Kalyani gives birth to a son out of wedlock and, fearing societal ostracization and her own inability to care for him, abandons the infant inside a moving cargo train. The baby is discovered and adopted by a resident of a nearby slum, who names him Surya. Growing up, Surya becomes highly intolerant of systemic injustice inflicted upon the underprivileged, while constantly questioning why his biological mother abandoned him; his only link to his past is the yellow shawl in which he was wrapped as an infant. Concurrently, Devaraj is a powerful, parallel-justice gang lord who uses violence to combat societal exploitation, making him both feared and respected. When Ramana, a tyrannical henchman working under Devaraj, terrorizes the local slum, Surya intercedes and kills him. Surya is arrested and subjected to police torture, but Devaraj intervenes to secure his release after realizing that Ramana's actions were predatory and that Surya's cause was genuine. Recognizing their shared ideology, Devaraj appoints Surya as his Thalapathi (commander) and chief confidant, forming an unbreakable bond of friendship.
Meanwhile, Arjun, an upright Indian Administrative Service (IAS) officer, is appointed as the city's new District Collector with a mandate to lawfully dismantle organized crime syndicates. Arjun is Kalyani's second son; after abandoning Surya, she had married Krishnamoorthy, a supportive man, and built a legitimate life as a physician and social worker, though she remains privately consumed by guilt over her lost firstborn. Concurrently, Surya is courted by Subbulaxmi, a Brahmin woman drawn to his protective nature. While Devaraj attempts to facilitate a marriage between them, Subbulaxmi’s traditionalist father fiercely objects to Surya’s violent lifestyle and instead arranges her marriage to Arjun.
As Arjun wages a legal campaign against Devaraj and Surya, Surya is confronted by Padma, Ramana's grieving widow. Riddled with guilt over leaving Padma destitute, Surya confesses his remorse to Devaraj. To secure Padma and her young daughter's safety and rehabilitation, Devaraj suggests that Surya marry her. Surya agrees, and over time, he earns the trust and affection of Padma and her child.
During a local medical camp, Kalyani notices Padma's daughter wrapped in the distinctive yellow shawl. Following inquiries and a subsequent police lineup identification, Kalyani and Krishnamoorthy deduce that Surya is her long-lost firstborn. Krishnamoorthy secretly confronts Surya to reveal his lineage. Shocked but protective of his mother's reputation, Surya requests that Krishnamoorthy keep his identity a secret from Kalyani, fearing the knowledge that her son became a notorious vigilante would devastate her. However, Kalyani eventually discovers the truth herself and confronts Surya. Overcome with maternal emotion, she pleads for peace; Surya relents, vowing never to harm his half-brother Arjun under any circumstance.
The long-standing feud between Devaraj and his chief underworld rival, Kalivardhan, reaches a crisis point. Surya confesses his true lineage to Devaraj, who is deeply moved that Surya intends to honor their friendship over his newfound family ties. Touched by this loyalty, Devaraj decides to peacefully surrender to Arjun to end the cycle of violence. However, as Devaraj and Surya arrive to meet Arjun, Kalivardhan's assassins ambush them. Surya is wounded, and Devaraj is fatally shot. Enraged on losing his only friend, the injured Surya storms Kalivardhan's compound and kills Kalivardhan and his henchmen. He surrenders to the police but is exonerated due to lack of witness testimony and evidence. Arjun is transferred to a different state and departs with Subbulaxmi, while Kalyani chooses to remain with Surya.
