Sivaraman, the owner of a construction firm, is threatened by Sooran, a goon who wants him to pay a hefty sum as hafta for attempting to raise a structure in an 'area that comes under his control'. The builder initially refuses to cough up the amount but finally agrees to pay him off after Sooran makes an attempt on the life of his son Murugan, an engineering student. As he is on his way to make the payment, Sivaraman meets with an accident and Murugan gets to know the trouble the goon is causing. How Murugan outsmarts Sooran to bring him to justice and how he helps his dad complete the structure is what the film is all about.
The title of the film and the names of the characters appearing in it give one enough reason to believe that the makers are devotees of Lord Muruga. Other than that, there is very little that is remarkable about this film which has a run-of-the-mill plot.
Starting from the script, the film is found lacking in quite a few departments. Take for instance some engineering college sequences. These leave you completely unconvinced and alienated from the plot and don't do anything to enhance the credibility of the story.
The film isn't without its strengths though. Its first strength is the music which has been scored by music director Ganesh Ragavendra. Most numbers in the film are enjoyable as is the background score which is apt. Cinematographer A S Senthil Kumar too seems to have done justice to his craft. Saravanan as Murugan, Navika as Meenakshi and Raja Simman as Sooran manage to look their parts while Ramesh Kanna and Devadarshini provide some much needed comic relief to the film.
At the end of it all, one is made to feel that if only the contributions of all its technicians were put to better use, Murugaatrupadai would have been a more engaging and entertaining film.
