Three Thai girls are mysteriously transported back to ancient times in director Preecha Songsakul's latest film Siyama: Village of Warriors. While sitting around discussing history, Ana (Thitima Maliwan), Gift (Nuttanan Juntarwet), and Bote (Boriboon Chanruang) suddenly fall into a time warp and end up in ancient Siam, smack in the middle of a civil war.
The ruthless Ong Mien army is advancing towards the capital city of Ayuthaya, and the small and quiet village of Siyama, a passage point to Ayuthaya, has become the unlikely first front of battle. Village leader Kru Jom (Sompob Benjatikul) is determined to protect his people at all costs, but not even his sorcery skills can hold off the swords of the entire Ong Mien army. With time and lives running short, it's up to Ana, Gift, and Bote to save Siyama by applying their history book knowledge.
Three young lives from the present are mysteriously destined to travel back in time through a portal to an old forgotten city. It is an era of civil war among the people of Siam where the fight is to protect the capital city of Ayuthaya from being conquered and overthrown. Bloodshed is about to unfold among the small group of villagers loyal to their land and prepared to battle to the death with the opposing military troops of Ong Mien, known for their cut throat, piercing swords.
Siyama led by, Kru Jom, uses religious sorcery to protect his small village located amidst a ravine populated by only a mere one thousand villagers and two hundred rooftops. By being the choice of passage towards the capital city of Ayuthaya, Siyama becomes a targeted obstacle for the gruesome military brigade of Ong Mien.
