"Deep underground, hundreds of meters beneath an ancient temple, lies a large diamond that can be used to create powerful weapons. Aliens steal it and attack the magical lizard guarding the diamond. Upon waking, the magical lizard discovers the diamond is missing and sets out to find it. He sends the giant guardian of Wat Arun (Temple of Dawn) to track it down and retrieve it before it's sent to the alien planet." - VCD Write Up. - Uses footage of Jumborg Ace and Giant (1974)
