This comes to Gauri Nanda's notice and she instructs Monica rather strongly to not believe Surendar's lies. Surendar decides to bring Monica to his ways after he realizes that Gauri Nanda has told the truth about him. Surendar convinces Monica that he has told about their relationship to his mother and takes her to his home to meet her. Under the belief that Surendar is indeed the telling the truth, she goes along with him to his house when in reality there is no one there at the said time. After reaching his home, Surendar engages physically with Monica and films it on video. Upon realizing Surendar's actions, Monica is distraught and commits suicide.
Gauri Nanda is furious over her sister's death and is raging with anger to hunt down Surendar and deliver justice. However, Surendar disappears and 'Nizhalgal' Ravi uses his influence to find him and approaches the police commissioner Rahman. Whether Rahman manages to find the whereabouts of Surendar forms the rest of the plot of Pagadi Aattam.
Surendar as the romeo is quite convincing in his role and does his part with complete justice. Likewise, Monica shines in her role convincing us of her potential to pull off mannerisms of a school-going girl as well as college-goer with ease. Post the tremendous performance in Dhuruvangal Pathinaaru, Rahman has once again played his part well in Pagadi Aattam. His antics to find the whereabouts of Surendar in the film are laudable. Rajasri plays an innocent mother and convinces us with her performance. 'Nizhalgal' Ravi, who comes as an influential person in the film makes us shudder each time he speaks in a powerful tone.
Director Ram K Chandran has narrated beautifully the punishment that gets served to boys who mislead young girls in the name of love for their lustful needs. The first half moves a bit slow as the story is focused more on the relationship between Surendar and Monica, but picks up its pace in the second half after the entry of Rahman. Although the second half is quite exciting, the climax is expected. Despite the obvious finish, the end result is quite satisfactory. Karthik Raja's two songs in the film are reminiscent of his father and 'Maestro' Ilaiyaraaja's music. He also hits the right spots in the background score department keeping it up with any fine crime thriller's score. Krishnaswamy's cinematography too is praiseworthy.
In short, Pagadi Aattam is watchable.
