Sachin Mani, while traveling enroute to Pondicherry to stop Nandita from marrying another guy, unfortunately will be taken into custody by the Railways Protection Force officer Arul Doss. He tries to pay the fine or somehow escape from the situation as soon as possible, but all to no vain. Sachin then narrates to his fellow defaulters about his complicate love story.
Sachien meets Nandita through a business advertisement call, and immediately initiates a friendship with her. He soon makes her fall for him, only to cut her off by stating that she is nothing more than a one-off flirt. A hurt and angry Nandita then decides to make his life hell, and comes up with various schemes to make him suffer. Under one such situation Sachin finally meets Nandita in person and instantly gets attracted to her.
Sachin then starts to pursue her, and after many attempts successfully captures Nandita's love. Meanwhile, he begins to take responsibility of his own life, and searches for a job. After a series of trails and error, he is appointed with a job by Chithra Lakshmanan, under a twisted deal. However, Sachin is unaware that he is Nandita's father. The rest of the plot revolves around how Sachin gets around the deal he made with Lakshmanan, and get successful in his life and love.
Sachin Mani debuts as an actor through Kathiruppor Pattiyal, and has delivered a decent performance. Nandita Swetha, looks pretty and has equally performed well. Other supporting actors like, Arul Doss, Appukutty, Chithra Lakshmanan, 'Motta' Rajendran and Sendrayan have done justice in playing their parts neatly.
Debutant Balaiya D Rajasekhar has attempted to make a simple love-hate-love romantic comedy film. Kathiruppor Pattiyal has all the essential commercial elements, and also succeeds in impressing the viewers with the humour sequence to a certain extend. Maybe, a little more detailing to the screenplay and characters could have made the movie more successful.
Sean Roldan has handled the music department and his scores are average. M Sukumar's cinematography skills come to the fore and he has shot well.
In short, Kathiruppor Pattiyal, is a decent watch.
