Southern thief) is a 1988 Indian Tamil-language action comedy film produced, written and directed by P. Kalaimani.

His cousin, Annakili, harbors romantic feelings for him, but her mother refuses to consider their marriage due to Kallan's impoverished state.

Kallan's mother encourages him to travel to Madras to earn a livelihood, enabling him to purchase land.

Upon arriving in Madras, Kallan encounters Radha, a wealthy and arrogant heiress, who, along with her friends, bullies and gets him arrested.

At the police station, Pandurangan, an absent-minded film production manager, mistakenly bails Kallan out, believing him to be a screenwriter.

Kallan joins forces with Ravi and Sulakshana, attempting to assert his position as Radha's husband.

Radha, with the assistance of her advocate Rao, obtains a court injunction, prohibiting Kallan from forcing her into intimate relations without her consent.

Kallan departs from Radha's residence, resumes his work as a stunt double, and eventually purchases a farmland, fulfilling his desire.

Seeking revenge, Chellakirukkan deceives Kathamuthu by falsely claiming that Annakili is having an illicit affair with Kallan.

At the village panchayat, Chellakirukkan falsely accuses Radha of orchestrating Annakili's rape by providing the sedative tablets.

The village women seize Chellakirukkan and shave his head, while Kallan forgives Kathamuthu at Annakili's request.
