A child finds a magic statue in a cave. This is a Thai idol that protects the world from an invasion by extraterrestrial giants. Edited from the Tsuburaya-Chaiyo co-production Jumborg Ace & Giant (1974), combining the special effects footage with newly shot drama scenes featuring a Taiwanese cast to create a loose adaptation of the original story that jettisons the connections to Tah Tien (1973) and Jumborg Ace (1973).
Unfortunately the movie Mars Men is not yet available on HBO Max.
