Her father Jayaprakash, a former income tax officer is in hiding after he is accused in by the police for the murder of his higher officer. On the other hand, a rowdy gang also try to capture the heroine's father.
In this situation, when Venkatesh comes to know that Nayanthara finds it tough without her father, he goes out to help her but conceals the truth about his profession. With the passage of time, love blossoms between the two. One day, when Jayaprakash's mother falls sick, he comes home to see her and Venkatesh utilizes this opportunity to arrest him. Realizing the real reason behind Venkatesh's attitude, Nayanthara gets angry with him. The rest of the story clears the knot about the murder and the aftermath.
Venkatesh dominates the first half of Babu Bangaram with his comedy and the second half with his terrific action sequences. Fitting well in the police role, he is able to portray the different characters in a great manner.
Nayanthara attracts the viewers by her beauty. Be it romance or comedy, she has done justice to her portions.
Brahmmanandham is the pillar for comedy in the film and guarantees many laughs along the course of the film. Sampath terrorizes in his antagonist role with Jayaprakash and Murali Sharma doing justice to their supporting roles.
The story of Selvi being a good old one, fails to impress the audience. Many sequences are too easily predicted and play a spoilsport to the momentum. Composer Ghibran's songs are quite average despite Richard Prasad's cinematography providing colorful magic on the screens especially in the dance sequences.
In short, Selvi is disappointing.
