Hallo

Sivaraman, once a brilliant lawyer, has fallen into a self-destructive spiral of drunkenness. He staggers through public scenes and court appearances as his career and health slip away. Chandy, a devout follower, repeatedly rescues him from brutal brawls, keeping him barely afloat.

After a brutal fight, Sivaraman earns the loyalty of three notorious rowdies: Vedakku Vakkan, Kolakolli, and Chattambi Ravi. They join his circle and become his loyalists, expanding his influence in the underworld. The alliance strengthens his public image while tightening his dependence on violence.

Sivaraman falls in love with Priya, but his father and brother vehemently oppose the relationship. Family pressure creates tension and foreshadows the tragedy to come.

On the night they plan to elope, Sivaraman is locked in a room by his family to stop the escape. Priya waits outside, unaware of the trap, hoping to see him soon. The cruel setup foreshadows the violence looming over their romance.

A group of gangsters spots Priya waiting late at night, molests her, and then kills her. Sivaraman learns of the brutal murder and is devastated beyond measure. The tragedy pushes him further into alcoholism and self-destruction.

Devastated and guilt-ridden, Sivaraman sinks deeper into alcoholism, neglecting clients and responsibilities. His public persona remains superficially intact, but his personal pain dominates every moment.

One day, he receives a phone call from Parvathi, a stranger who claims to be the daughter of a local Marwari banker. She says her life is in grave danger and pleads for his help.

To protect Parvathi, he brings her home and pretends to be her husband. He becomes her shield against a powerful family and a bank's shadowy controls. Their alliance begins amid suspicion and danger.

Parvathi's greedy relatives, led by Bada Bhai, intensify their threat as they seek control of her life and fortune. Sivaraman faces them in a battle that blends brains and brawn as he outmaneuvers their schemes. The confrontation tests his resolve and his capacity to protect Parvathi.

As the conflict unfolds, Parvathi is impressed by Sivaraman's brilliance and resilience. Her respect grows into love as she witnesses the danger he risks to shield her. Their bond strengthens amid the chaos.

The danger expands into a broader power struggle around the bank Dalal & Dalal, and Sivaraman uses his legal wit to counter the relatives' plots. He coordinates with Parvathi, leveraging strategy and his street-hardened toughness to tilt the balance. The clash leaves both sides wary of what comes next.

With danger still looming, a fragile partnership forms between Sivaraman and Parvathi as they decide to face the odds together. Her feelings for him have solidified into love, and his battered genius finally finds a reason to keep fighting. The film ends on a note of cautious hope as they plan their next move.
