Maragatha Naanayam is rather an unusual title, to begin with. Which is why it starts with a voiceover that narrates the subtext. Irumporai Raja, a Chola king chances upon a powerful emerald, Maragatha Naanayam, with which, he conquers most of the kingdoms down South. Much like Gollum from the Lord of The Rings series, Maragatha Naanayam becomes an obsession for Irumporai over a period of time.
Senguttuvan (Aadhi) is in need of big money to clear his huge debts. He joins hands with a small time smuggler Ilango (Daniel) who introduces him to Nochikuppam Ramadoss (Ramadoss), a veteran in the field.
Not happy with the petty plunders, Senguttuvan is on the lookout for something big. Around the same time, a Chinese smuggler comes to the city eyeing to loot the precious Maragatha Naanayam belonging to a king of Irumporai, who is rumored to be a ghost now guarding the stone. And anyone who touches the gem would get killed and there are as many as 132 men who have died earlier laying their hands on it.
In the beginning, the director takes a little while to get to the story. But once he does that, the film travels at a uniform pace till the climax making the audience laugh out loud till the end. The film could work well if you understand that the director’s objective is to give a light-hearted film and don’t much question the logic.
