In 1897, the "Poisoned Knife" clan broke into the royal palace of Thailand to steal the royal antiques, but the thieves didn't escape with their lives. Before their deaths, they hid the antiques somewhere close to the palace. Today, Wisa, the mafia boss whose ancestors masterminded the theft of the antiques, wants to find them. He hires Patrick, the former Director of the U.S. military's National Subterranean Exploration Unit, to search for the lost antiques. When they steal the antiques from the temple, it's up to Krit, with the help of Praifa, an archaeology student, to retrieve them. Together, they fight against the powerful and greedy group of thugs. Will they be able to rescue Thailand's national treasure and protect the world from evil?
