Ramu, the elder son takes the blame for the crime to save Murthy, his young half-brother.

In his escape, the fugitive can count on the indestructible support of two women, Vasantha and Meena who love him (the first one officially and the second one secretly).

Ramu is chased by the policeman Mogan, persuaded by his guilt and also by criminal Kannan and his band, who want into his colossal fortune, conspiring since the beginning, with Varadarajan, much less honest than we could hope for of a lawyer.

Ramu will finally emerge as innocent thanks to the testimony swapping with his girlfriend, Parvathi alias Chandra.

Towards the end of its trip, as ultimate test, pricked by a dangerous snake, Ramu owes his safety only to the older brother of his beloved deceased Vasantha, the fairground entertainer Muthaiyandhi.
