[3] Sundaram is an innocent band musician who lives with his physically challenged sister Sita in a village.

On the other hand, Madras city Police department is shocked by a series of diamond thefts.

But Inspector Mohan suspects the thief to be Ranjith Kumar, who is actually a wealthy diamond businessman on the account that whenever a theft occurs, he is present there.

He convinces Sundaram to act like Ranjith in front of society as he is a heart patient and requires a treatment.

In the village, due to heavy floods, Sita loses everything and comes in search of her brother to Madras with her dog Mothy.

Sundaram finds Ranjith is actually a thief and plans a grand diamond loot.

Ranjith steals a huge amount of diamonds, but Sundaram replaces him by attacking him and leaves the place.

One of the stolen diamond pieces has a transmitter and police follow the jewels with the help of it.

The song "Kannai Nambathey" was remixed by G. V. Prakash Kumar in Enakku Innoru Per Irukku (2016).

He concluded the review saying it is like a bittersweet mix when you think that this film, which speaks of Vaathiyar's (Ramachandran's nickname) greatness, turned out to be a Tamil adaptation of the Hindi film Sacha Jhutha, couldn't they get a similar plot in Tamil ?.
