[3] The series is a story about searching for American soldiers lost in the Vietnam War, the Phuri tribe, and the mythical serpent Phaya Nak, which is said to be protecting the kingdom.
[1] Dave, a former special forces officer, and his partner, Draco, want to find answers to their questions about the Phaya Nak, a woman, a hidden city that Dave often dreams about when he sleeps, and a mission to build a bridge across the Mekong that is threatened by international drug-trafficking organization.
As a result, they meet Dr. Kim, a young anthropologist who might be the one to lead them to the answers to their questions, beginning a journey involving mysteries from the tutelary of the Mekong, Phaya Nak.
[4] Two CG production houses, with a total team of 40 people, were responsible for creating the image of Phaya Nak.
Other criticisms of the show are that the CG is unrealistic, that the story progression is not entertaining, that the acting of the performers was not up to par, as well as that the scene in which the character Dave catches Phaya Nak with a lasso is unrealistic, although some have said that the scene is entertaining.
