Unnikrishnan joins a law college and is ragged by seniors led by Pappan. Pappan violently thrashes him, and Unnikrishnan is insulted in front of girls. In retaliation, he stabs Pappan in the college corridor.

G.P., Pappan's political mentor, orders his goons to bring Unnikrishnan to the fold. Seeing his potential, G.P. inducts him into the party. He also brokers a truce between Pappan and Unnikrishnan, steering their conflict toward political engagement rather than vendetta.

The Government of Kerala introduces a bill on self-financing colleges. The party under G.P. opposes the bill and launches a student agitation campaign. Unnikrishnan is appointed as the leader of the movement, channeling student anger into organized action.

G.P. aims to spread violence by publicly immolating Unnikrishnan in front of police and the press. The plan goes ahead and Unnikrishnan is killed. His death is used as a powerful weapon against the government, while also becoming a personal blow to his family.

Harikrishnan, Unnikrishnan's elder brother, travels from Mumbai to Kerala to perform the funeral rituals. He arrives to lay his brother to rest and to understand the circumstances of the death. His arrival marks the shift from tragedy to pursuit of truth.

Harikrishnan suspects foul play behind Unnikrishnan's death and resolves to uncover the truth. He faces resistance from the college management, cops, and local politicians. His attempts to secure an inquiry from the Chief Minister are blocked.

Harikrishnan meets Meera, an aggressive journalist who witnessed Unnikrishnan's death. Meera's account provides crucial information that challenges the official narrative. Together they pursue the story and the truth behind the killing.

As the investigation progresses, Harikrishnan learns about G.P.'s plans to escalate violence against the government. Meera's reporting helps surface these manipulations and the political motives behind the death. The movement's momentum continues to grow in response.

Harikrishnan faces multiple assaults from G.P.'s hoodlums, but he stands his ground. He endures beatings and threats while seeking justice for his brother. His resilience earns support from students and sympathetic onlookers.

In a final stand, Harikrishnan, with the help of college students, defeats the hoodlums and burns G.P. alive. The violent mentor's death signals a turning point in the struggle between student activism and political corruption. The community absorbs the shock of the brutal ending.

Unnikrishnan's death leaves his family devastated, while the movement clings to his memory as a symbol against the government's measures. The government faces backlash as public opinion shifts in response to the violence and its causes. The film closes by showing the high cost of political violence on individuals.
