Ubercorn is DJing a funky party at the Go Jet Academy for the Go Jetters and cadets to enjoy, when suddenly Grandmaster Glitch gatecrashes with his mighty electric guitar. Glitch starts playing rock music with his Grimbots backing him up on the drums. Although Kyan is loving the music, it is LOUD and starts to crack the Academy statues. Ubercorn shuts down Glitch's raucous rock performance leaving the Grandmaster determined to find a brand new crowd who'll love his loud music. He decides to travel to Chian in China so that the 1000-strong Terracotta Army can be his adoring audience. But when he unleashes his rock guitar, the music is so loud it causes the fragile terracotta statues to jump around and the ancient army are at risk of breaking! The Go Jetters need click-ons to save the statues from smashing to the ground.

Grandmaster Glitch is visiting London and spots the perfect souvenir at a riverside stall - a majestic hat that was clearly made for a Grandmaster! But when he finds he has no money, he decides to raise some by working as a tour guide on the River Thames. The Go Jetters are also visiting London while Lars helps to fix his favourite his bridge - Tower Bridge. Ubercorn explains that this amazing bridge can be raised to allow tall river traffic to pass safely beneath. While Lars goes to fix Tower Bridge, Xuli, Kyan and Foz jump onto a riverboat tour, unaware that they are in fact boarding Grim HQ! Before they can jump ship, Glitch sets sail, giving out his very own glitchy facts and spending his customers' money on his Union Jack hat. But when the hat blows away in the breeze and Glitch gives chase, he puts tourists, boats and Tower Bridge itself in danger.
