Storyline: The storyline of the film Sathru revolves around a cat-and-mouse game between an upright young policeman and five criminals.
The film begins with a Koothu scene in which the cast explains what will happen at the drama in the coming days. They say it’s about Soorasamharam, and Lord Velan will be destroying the enemies there. Kathir plays Kathiresan, a young upstanding cop who believes in thrashing criminals to get them to confess to their crimes. Despite his superior’s chastisement for his violent attitude, nothing affects him, and he is not someone who is acting this way only because he is young. It’s second nature to him, according to his co-workers. In the first few scenes, we also meet his girlfriend, played by Srushti Dange.
Kathir and his family are in danger after he outwits a gang of robbers and saves the life of an abducted boy with the help of his sharp mind. While he is saving the boy, one of the physically disabled youngsters in their group is killed. The gang members lose their cool as a result of this. They are cruel against everyone else, and the only reason they go to such lengths is to make money and calm down, but they lament the loss of their gang member in a pitiful manner. In the first few episodes, the audience can also sympathise with them because of the police brutality.
Suja Varunee’s character begins with a sense of suspense and hope, but the characterization quickly falls flat. Laguparan, who played Prabha, the gang leader in Rattinam, is a fascinating character to watch, and he has done an excellent job in his role. His demeanour and behaving perfectly capture the ominous atmosphere. Kathir is fast and well-dressed. Though he seems to pause for a moment before emoting in nearly every scene, he shines in action sequences. Ponvannan does an excellent job as Kathir’s dad.
The film also depicts how the police lose out on the finer points of life and become a laughingstock due to their ineptness. Suja Varunee’s accomplice, the boy, is very refreshing, particularly when he switches sides. Throughout the last 30 minutes of the film, he is completely at ease. The film’s background score complements the genre as well as the camera work. It might have been a crisp thriller if the storyline had been a little tighter.
