The story begins at the time of the end of the reign of the last kings of India in our days (the 1970s).

Sanguili (M. N. Nambiar) is a man without faith nor law, who extorts, kidnaps, if necessary, which murders and desires for a very long time, the fabulous treasure of the king of neighborhood, (S. V. Ramadoss).

At the time of seizing it, where he fails moreover, he kills the king and puts the blame of this heinous crime on his wife, the queen, then pregnant.

All the indications accuse the poor queen, who eventually volatilizes.

The only one, Velamma (G. Sakunthala), who could acquit her, is silenced by the threats of Sanguili. Some years passed.

Ilango (MGR), a particularly very effective secret agent (grace, among others, in its total control of the yoga and to his knowledge complete of the well done of healing plants, inherited from his father, Moghan Ram (K. Nadarajan (or) K. Nadaraja Iyer), an herbalist of great renown) is sent by his superiors with a mission to stop the actions of Sanguili.

A map is in the center of this case, because it indicates the location exact of the famous treasure, so looked for, for years by Sanguili.
