The battle with the ogre is simulated from the folk tale Thach Sanh with a filial and honest boy with a beautiful relationship with Princess Quynh Nga. Adapting from a plot that has been infiltrated into the blood and blood of many Vietnamese people with the spirit of respect for identity but also needing novelty is a big challenge for the film crew The War with the Elves. Based on the famous fairy tale, the film has built a fictional plot. While the country was at peace, the invaders and King Hung's army had to confront a mighty opponent.

However, the higher task of Thach Sanh is to destroy the ogre to save the whole country from the invasion.
