The Shadow Syndicate of Public Enemy No. 1 - "The Hood" - has lost a prominent ally with the loss of Hudatvia to WIN and seeks to become the richest and most powerful army in the Solar System. The Hood's younger, nobler half-brother Kyrano Belangant and his family have found sanctuary with billionaire industrialist and ex-ISC astronaut Jeff Tracy and his own family. Accompanied by Hiram K. "Brains" Hackenbacker and his son Fermat; Jeff and Kyrano take their families including Jeff's sons (Scott, John, Virgil, Gordon and Alan) and mother Ruth along with Kyrano's wife (Onaha) and daughter (Tin-Tin) to an uncharted tropical archipelago in the South Pacific. It is here they build the secret headquarters of International Rescue, dedicated to helping those in need whenever disasters strike. Along with Lady Penelope and Parker in England, International Rescue is known by their machines to counter the Hood's operations - the Thunderbirds.
