Kalaiarasan and Prasanna are friends from their childhood. Since the latter is an orphan, he grows up under the care of Kalaiarasan's parents and house. Prasanna works at a mechanic shop while his friend searches for a proper occupation.

In this situation, Dhaniska's parents suddenly decide to get her married to their relative. Fearing the worst if she speaks out about her relationship, runs away from her house, and seeks help from Prasanna to solve the situation by getting her married to Kalaiarasan. 

But, everything breaks apart when Dhaniska's mother ends her life suddenly, and another group of rowdies corner Prasanna to seek vengeance. The rest of the plot revolves around how Kalaiarasan and Prasanna tackle their situation and finding out what happened to their love lives. 

After a lot of hurdles Kaalakkoothu finally hit the screens yesterday. Both Kalaiarasan and Prasanna have given an impressive performance. Dhansika pulls of her bold character really well. Srushti Dange has very little to perform other than being the Prasanna's love interest. 

Debutant M Nagarajan has attempted to make a rural tragic love story. Though he succeeds in canning the tragic portions well, he fails to elicit the desired reaction for the sequence. That's because he falls short on the screenplay front and has faltered by placing several unnecessary scenes. Maybe, the film could have been better if it was scripted differently. 

Justin Prabhakaran has handled the music department and his songs and background scores are pleasant  to the ears. PV Shankar's cinematography skills come tot he fore and he has shot really well.

In short, Kaalakkoothu could have been better.
