On a foggy Okinawan night, a stranger disrupts the Zanadu family’s first island-unique dinner at a seafood restaurant. His violent search for a flying microbot leaves the family devastated, with Gabe and Alex Zanadu’s mother unconscious on the floor. An Okinawan government official’s son, Mike, whose father was also assaulted, leads the boys in a search for the fleeing thugs. Unsuccessful in bringing the attackers to justice, Gabe and Alex, their two dogs, Thunder and Lightning, and their new friends, Mike and his older sister, Crystal, is then hunted by the Okinawan and mainland-Japan mafia. When the Japanese mafia grabs Alex and Crystal, the race is on for Gabe and Mike, along with the dogs, to find and free their siblings before they meet an untimely end.
