Plot 
King Seevaka of Pandya Kingdom ruled the Kingdom through its capital Madurai. But, under the bad influence of the minister, Kutilan (Balasubramaniam) he changed his capital to Tirunelveli where Kutilan has support. Kutilan wants to rule the kingdom. So, he tried to make the king fall. Rajaguru (Sama) told the king that the capital is not so strong. He said that he would make the Kingdom good with doing a yagna and want to have a special room for him. Princess Manonmani, who dreamt of Chera King Purushottaman fell in love with him as he also does. But, Kutilan wants Manonmani to marry Baladeva his son. Soon, the Rajaguru who was good hearted wanted the princess to marry Purushottaman to get out of  Kutilan's evil trap. He asked Seevaka and Manonmani to come to a secret pathway under the palace connecting to the Rajaguru's ashram and Chera's Army Place. Seevaka told this to Kutilan. But,

Manonmani, the Pandya princess (Rajakumari), falls in love in her dream with a prince Purushottaman (Chinnappa) who too does likewise with each unaware of the other's identity! But their love grows deeper in their hearts. The Rajaguru (Sama) is keen on bringing the two kingdoms together and builds a ‘secret way' from one kingdom to the other. However, the King (Perumal) is under the influence of the scheming minister Kutilan, (Balasubramaniam, the name was obviously inspired by the celebrated Kautilya, Chanakya.) The minister's son Balaiah has an eye on the princess, and the father and son try to manipulate the king's mind…

After many twists, the lovers meet and the two kingdoms come together and the ‘dream lovers' marry….  An interesting tale of kings, princes and princesses, Rajaguru and evil ministers, Manonmani was a box office hit with Rajakumari and Chinnappa stealing the show. Sakunthala (Mrs. Chinnappa in private life) played the princess's companion, while the ‘comedy track' was taken care of by the inimitable Krishnan-Mathuram supported by Narayana Rao.
