Part I 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 III was to depict Naresuan's military and leadership skills and the expansion of the Siamese kingdom.
