Near a remote Buddhist monastery, a young man falls in love with his sister and gets her pregnant. After a monk finds out, the young man becomes an assistant to a master sculptor, only to proceed to complicate matters with his affairs.
After a valiant Thai boy is brutally murdered by a gang of archeological looters, his soul is joined with the Hindu god Hanuman, who teams up with Ultraman and his brethren against familiar Ultra-foes unleashed by a weather control experiment gone awry, in this influential Thai-Japanese co-production.
The film consists of re-edited material from the original television series Ultraman. Episodes 1, 8, 26, and 27 were used for the film. They were narrated by Hikari Urano as an "Ultraman Documentary". Allegedly only one new scene was shot, and that some parts of the movie where shot in black and white for unknown reasons. The movie screened at the same time as the Toho movie King Kong Escapes.
