After some years, Udayan and his fellow slaves staged a mutiny on the ship, killing the captain and releasing themselves.

Udayan ran away and became a rich merchant after finding the lost treasures of Ali Raja and his daughter Lalia.

Years made people forget Udayan, and no one was able to recognize him in his new attire and lifestyle, except Queen Parvathi, who understood him just at a glimpse.

Meanwhile, Udayan was hatching a plot to trap Perumana Kuruppu after learning that the crown and sceptre of Kolathiri Raja were in his custody, as King Devan declared it missing.

At the trial, he declared that the old Raja had given the crown and staff to him for attempting to rescue the king from attack, and he challenged the prosecutors that they have no evidence against him for betrayal and robbery.

It was at this moment that Lalia entered into the court to declare her true identity as Princess Laila – the heir apparent of Ali Raja and presented herself as the sole eyewitness to the incident.

Kammaran repeats the old strategy with the assistance of the Kompan, who asked the king to come directly with a tribute in order to prevent an attack.

However, understanding the trap, Devan comes with a chest with soldiers hiding inside, and they attack Kammaran and Kompan in surprise.

In the meantime, Prince Chandran through his close friend Kannan, who was Kammaran's son; discovered Udayan's double cross.

Hearing his son's surrender without a fight made King Devan furious, so he went to Udayan's palace to challenge him.

The film was photographed in CinemaScope format and was converted to 70 mm blow-up prints with 6-track magnetic stereo sound during post-production.
