Zero-X, a manned exploration mission crashes during lift-off on its maiden flight. Two years later an investigative committee finally concludes sabotage, and decides to call on the services of International Rescue to oversee security at the impending second launch. The second Zero-X successfully reaches its destination, but encounters unexpected hazards, ultimately leading to another call for assistance on its return to Earth. International Rescue respond, and once again Thunderbirds are GO!

Dangerous missions are the bread and butter of the Thunderbirds, a high-tech secret force employed by the government. Led by Jeff Tracy (Bill Paxton), the Thunderbirds are at the top of their game, but their nemesis, The Hood (Ben Kingsley), has landed on their island and is attempting a coup by using the team’s rescue vehicles. He’ll soon discover that the Thunderbirds won’t go down.
