Plot Summary

Shanmugham lives a tranquil and modest life in Ranni with his wife Lalitha and their two children. Once a celebrated stuntman in Malayalam and Tamil cinema, a tragic on-set accident resulted in the loss of his close friend Anbu and ended Shanmugham’s film career. Ever since, Shanmugham has led a quiet life, cherishing his aging black Ambassador car—his most treasured possession and a symbol of his past glory, memories of friendship, and identity.

One day, Shanmugham’s college-going son Pavi and his friends take the Ambassador out for a joyride without permission and crash it. Though initially angry, Benz entrusts it to his friend Kuttichan, a local mechanic, for repairs, and shortly after, travels to Chennai to attend the funeral of his old stuntmaster.

Upon return, Shanmugham is shocked to discover the car has been seized by police, suspiciously connected to marijuana smuggling—contrary to his innocence, the police suspect him due to a package hidden inside the vehicle. Confronting an arrogant SI Benny and the senior officer CI George Mathan, Benz pleads for justice but is coerced into a humiliating deal, driving the police officers to social functions and then to a remote farmhouse.

At the farmhouse, Benz uncovers horrifying truths about a conspiracy involving the death of Sudheesh’s alleged ex-boyfriend, which police cover up by hiding the body in Benz’s car to protect political interests and police reputations.

Meanwhile, Pavi goes missing, and Benz learns that Pavi’s body lies concealed in a remote location, a victim of honor killing orchestrated by CI George, who seeks to suppress the scandal threatening his position and family prestige.

Benz embarks on a relentless quest for truth and justice, exposing corruption and seeking vengeance against those who destroyed his family. The film’s climax involves tense confrontations, revelations of deep-seated corruption, and Benz’s transformation from a grieving father to a man on a mission to reclaim dignity and justice.

The film ends on a poignant note, emphasizing “Thudarum” — continuation, implying the ongoing struggle against injustice and the enduring spirit of resilience.
