A giant tower catches fire, and Scott & Virgil determine to save a trapped family, they need to use a dangerous new gas.
Another well-crafted episode, this installment depicts a giant skyscraper said to contain a complete city inside, which we unfortunately don't get to see, but there's plenty of action and drama to satisfy any Thunderbirds fan. Perhaps showing its age, the script does take a dig at women drivers and showcases a particularly dangerous one.
