Sirimal is a bright young poor boy living in a rural village area in Sri Lanka. When he passes the all-island scholarship exam with becoming the first place in the island, he wins a chance to attend a wealthy school in Colombo. Despite his many cries and tears to leave his hometown and family, he travels to Colombo with his father. Sirimal does well in the school, gaining many friends as well as a spoiled rival, Shehan.

When the School drama teacher announces about their annual Drama Competition, Sirimal is determined to get the main role, which is the King's role. However, he wins the role of his dreams, but he hasn't got enough money for the costume. Shehan, who also wanted that role, encourages Sirimal to swap roles, which is the Rajadrohiya's role. But Sirimal doesn't want to.

Sirimal and his best friend tries to earn money to buy the costume by doing part time jobs, such as shoe polishing and working in a store. But Sirimal's father insists they get help from the village's dancing teacher, who gives Sirimal his king costume. But the crown is too big for Sirimal.

The drama teacher tells Sirimal to make a ring out of cloth and cotton. After that he will be able to wear the crown no matter how big it is. On the day of the performance, Shehan steals the cotton ring from Sirimal while he's in the washroom. After a tearful tantrum, the drama teacher decides to give Shehan the king's role and Sirimal the cheap rajadrohiya role. Sirimal protests, but he gives an extraordinary performance as the Rajadrohiya and wins the best actor award. The film ends with Sirimal acting as the king in their village drama competition.
