Glitch has attached huge rocket boosters to Grim HQ in an attempt to become the first Grandmaster in space. As he thunders up into the night sky, it looks like he may actually do it this time. Then the boosters splutter to a stop and he crashes back to Earth. Glitch clambers to his feet amongst the wreckage of Grim HQ and demands the Grimbots find him another spaceship. Meanwhile, the Go Jetters arrive at the Seattle Space Needle, a huge spire with a futuristic viewing platform made to look like a flying saucer. Suddenly the ground begins to shake. Kyan thinks it's his stomach, Xuli thinks it's an earthquake, but Foz spots the real cause - Glitch has attached four of his huge rockets to the saucer to turn the Space Needle into a spaceship!

When Grim HQ's heating gets stuck on, Glitch looks for a cold place to land and cool down. Meanwhile, the Go Jetters enjoy the cool sights of Harbin Ice City in China. Every year sculptors at the festival create realistic models of world-famous landmarks from blocks of ice, and Lars is attempting to carve the Eiffel Tower. Suddenly the sculptures around them begin to melt. The team investigates why everything is heating up and discovers a red hot Grim HQ sat in the middle of the festival. If they don't move it quickly, Harbin Ice City will melt!
