Atharvaa is a rookie police officer who encounters a dangerous soldier-turned-criminal in the trailer for Thanal. The makers unveiled the film's trailer on Sunday.

Atharvaa and a group of his police friends, also newbies, are seen encountering a gang of criminals dressed as workers in the trailer. Ashwin Kakumanu is introduced as the villain, who reveals that he is a former army man. When the police officers try to confront the criminals at one instant, one amongst them is killed by the criminal gang, leading to a cop-criminal chase. How they catch the criminal gang, and the identity behind the villains, seems to form the crux of the film.

In an earlier interview with CE, the director of the action-thriller, Ravindra Madhava, said the story follows a painful event that turns one person into a hero and the other into a villain and what will happen when the two meet each other. The film features Ashwin Kakumanu as an antagonist for the first time. Thanal stars Lavanya Tripathi as the female lead.

Apart from the lead actors, Thanal also stars Sha Ra, Barani, Selva, Azhagam Perumal, Bose Venkat, Lakshmi Priya, Bhaarath, Thoufiq, Sarvhaa and Pradeep Vijayan in supporting roles. With Justin Prabhakaran composing the music, the Atharvaa-starrer will have cinematography and editing by Sakthi Saravanan and Kalaivanan, respectively.

Thanal is gearing up to hit theatres on September 12. It will be releasing alongside Arjun Das' Bomb, Kumaran Thangarajan's Kumaara Sambavam, and GV Prakash's Blackmail.
