In a carefully planned attack on the planets of our solar system, the aliens have disabled the orbital probes which made up the most important part of the Earth Defence System. With the probes in pieces there's no way for the human race to defend itself as all the missile guidance systems on the planet make use of its telemetry data! Curse our short-sightedness in putting all our eggs into one basket... a basket of death! But it gets worse. They are using this Space-Radar blackout to fire a giant alien Hive of Indescribable Terror straight at the Earth's surface. Inside the Hive are billions of tiny insects, bred with the single dire purpose in mind... to eat tea leaves!
If the Hive enters our atmosphere and ruptures then all the tea in the world will be consumed by a swarm of pure evil! Without tea the British Empire's stiff upper lips will wilt and flap horribly, leading to the downfall of civilization itself!. Our only chance is to entrust the future of the entire world to one man... Jetman! With his trusty Rocket Ship, Jetpack, Quadroplasmic Lasertronic Disrupter Rifle, and the help of our foremost military mind, he might just be able to carve a swathe through the alien forces and repair our defense probes before the unthinkable happens.
