Part 1 deals with Naresuan's boyhood, when he was taken hostage by Burmese King Bayinnaung to keep the vassal Ayutthaya Kingdom subservient. During this time, he was a novice Buddhist monk under the tutelage of a wise father-figure monk (Sorapong Chatree). Part II depicts Naresuan as a young adult prince, already a formidable military strategist, as he leads his army on exploits against breakaway kingdoms for King Bayinnaung's successor, King Nonthabureng, and eventually breaks away to declare sovereignty for Siam. Part 3 was to depict Naresuan's military and leadership skills and the expansion of the Siamese kingdom.
