Coolie

Loganathan leverages money to secure the union leader's cooperation and quell potential protests at the factory. During a salary negotiation, the union leader pretends to represent the workers while secretly acting in Loganathan's interest. This corruption paves the way for his continued interference in labor matters.

Karna mobilizes his coworkers to demand a larger pay raise and builds broad support. With this backing, he takes over as the union leader and becomes the voice of the workers. His rise challenges Loganathan's influence over the workforce.

Loganathan invites Karna to a party and hands him new clothes and a car in an attempt to sway him. Karna rejects the temptation, damages the car, discards the clothes, and declares that he will stay poor until workers are treated fairly. The gesture reveals Loganathan's ongoing strategy to influence key figures.

Karna's sister is a close friend of Vimala, Loganathan's daughter, and Vimala admires Karna's character. Their bond foreshadows how personal relationships become central to the unfolding conflict. The family connections complicate loyalties at the factory.

Loganathan's son falls in love with Karna's sister, and the couple marries with Loganathan's support. The union strengthens ties between the two families and shifts the balance of influence at home and in the factory. The wedding signals a new phase in the power dynamics around the business.

Following the wedding, Loganathan sends his son to work in Mumbai and dispatches Karna's sister to support the business in their hometown. The moves reflect Loganathan's continued control over the family and the business empire. The separation also deepens personal strain within the family.

Loganathan lies to his daughter-in-law, claiming he has cancer and needs money for treatment. The deception creates distrust within the household and accelerates a change in Karna's sister, who becomes a strict businesswoman and grows distant from Karna. The rift foreshadows the growing tension between labor leadership and family loyalties.

Despite Loganathan's objections, Karna and Vimala marry, demonstrating their commitment to each other. Loganathan's disapproval heightens the conflict between family loyalty and business interests. The marriage becomes a catalyst for the final power struggle at the factory.

Karna is suspended for a day after he accidentally touches the wrong switch, pausing factory operations. The incident strains his relationship with his sister and distracts workers from their wage demands. It also adds to the mounting tensions in the workplace.

Karna fights a fellow worker who has been manipulated by Loganathan to create trouble in the factory. The worker later claims the fight is Karna's fault because of his love for Karna's sister, weakening Karna's standing with the workers. The incident accelerates the erosion of Karna's support.

Loganathan schemes to burn down the factory to collect an insurance payout. A worker who had been used to sow trouble exposes the plot, raising the stakes for everyone involved. The plan further proves Loganathan's willingness to go to extreme lengths to preserve his empire.

The old union leader collaborates with Loganathan to murder Karna, hoping to regain control of the factory. He also plots to kill Loganathan in revenge for past jail issues, setting up a dangerous double-cross. The conspiracy pulls multiple factions toward a dramatic climax.

The old union leader breaks into Loganathan's house, beats him, and runs a jeep over his legs. Karna arrives and saves Loganathan, turning the tide on the conspirators. This act reshapes loyalties and the trajectory of the feud.

Loganathan ends up in a wheelchair but has become a better person who finally accepts Karna and Vimala's marriage. The film closes with a more hopeful, reconciled family and a tempered balance of power at the factory.
