This is an epic saga about four identical quadruplets were separated at birth. A rich industrialist is secretly married to a woman, who is expecting their child. His brother, wishing to eliminate any potential rivals to the family property, sets her up to be killed by hired goons, who are also ordered to kill the babies.

The leader of the goons, (Santhana Bharathi), having no desire to kill the identical quadruplets, takes one with him (Michael), drops one in an orphanage (Raju), one in a temple (Kameshwaran) who is picked by Palakkad Mani Iyer (Delhi Ganesh), and one in a car (Madhan) that belongs to the babies' father.

Years roll by and all the four kids grow up and even though all of them physically look alike, they have completely different mannerism and personalities. The crux of the story details how each of these identical quadruplets' lives become intertwined, and how each of them comes to realise their true history. Will they succeed in reuniting their family and punishing their uncle for separating their family?
