Brazilian-Japanese gangster Mario rescues his Chinese girlfriend Kei as she's about to be deported from Japan. Desperate to escape, he hides in Tokyo's booming Japanese-Portuguese community and seeks passage from the country from a Russian mobster. To meet his price, they hold up a bigtime drug deal between the Chinese Mafia and the local Yakuza.

When heads of state gather at the G8 summit in Japan, Guilala -- the intergalactic monster that had been banished from the earth in The X from Outer Space -- returns to ravage the Japanese countryside and threaten the world leaders. Military strikes prove futile against the beast, but a reporter learns that one rural community possesses a strange ritual that might influence the creature. Minoru Kawasaki directs this campy satire.
