In this episode, Grandmaster Glitch goes on a desert adventure to uncover a mysterious lost city. If only it hadn't already been discovered! As Glitch attempts to beat a group of tourists to Petra in Jordan, he crashes his Grimbler in the Siq gorge. Vibrations from the Grimblers engines shake the surrounding area, causing the treasury building to shake apart. Can the Go Jetters save the ancient city?

In this episode, the Go Jetters arrive at the Bonneville Salt Flats in Utah, USA - a huge dry lakebed that's perfect for high-speed driving. Lars unveils the Turbo Zoomster, a racecar made for Xuli to break the Go Jet land speed record. Suddenly, Grandmaster Glitch arrives at the wheel of his suped-up dragster. He once lost a race to the current record holder, Ubercorn, and now he's back for a second go.
