Entertainment Desk:Director Hari introduced Suriya as Durai Singam in the first Singam. He was as a reluctant police officer with strong family values, who preferred to run a provision store in Nallur, a small village in Tamil Nadu, over policing. He was raw and he had his own ways of dealing with problems of the villagers. He was always game for a fist fight but was also open to a dialogue. The first part was all about Durai Singam overcoming his own mental barriers and convincing himself to stick to khaki.
In Singam 2, he had no confusions or doubts. His experience in Chennai had made him more skilled in dealing with hardened criminals. He went undercover, gathered evidence and took out criminals who were involved in a drug cartel that had turned Thoothukudi into the nerve centre for drug-trafficking. The climax of second part ended in South Africa, with the arrest of drug lord Danny.
In Si3, Durai Singam has grown more focused and advanced as he gets ready to finish an international crime syndicate, run by Vitthal Prasad (played by Thakur Anoop Singh). The film is set in the backdrop of a volatile situation in Telugu states after Telangana was carved out of Andhra Pradesh. Durai Singam is called in from Tamil Nadu by the AP government to investigate the murder of the police commissioner of Vizag, as the state police department shows no progress in the case.
As soon as he arrives in Vizag, he begins his police work, gathers evidence and goes after big shots, including Vitthal, who remote-controls his Indian dealings from Sydney. An Australian citizen and the son of an Indian central minister, Vitthal runs his illegal activities in India with impunity. He has turned the port city, Vizag, into his private dumping yard for e-waste and the medical waste that is generated in Australia. And when the police commissioner, played by Jayaprakash, threatened to blow the whistle on Vitthal�s crimes, he was killed.
Hari has continued to unapologetically follow his style of entertainment as he has further jazzed up the larger-than-life cop with high-voltage punchlines and action sequences.
