It is the year 2233 and human kind has spread throughout the galaxy. To stay in contact with one another mail is delivered by the universal corporation Interstellar Couriers™.
Loosely named "space jumpers" by the public, these bona-fide postmen can teleport from planet to planet to deliver the fastest mail in the Milky Way.
One such average-Joe space jumper is sent to an unusually remote planet to deliver a package. However, when he lands on the planet he is suddenly attacked.
What he assumed to be a standard piece of machinery turns about to be part of a warp gate being built to send an army to planet Earth.
The space-jumper barely manages to escape but in the process his suit is damaged, cutting him off from Earth. Not only that, but the AI has become corrupted leaving it a schizophrenic, static hologram.
Dealing with a mentally unstable AI, his teleporter becoming a deadly weapon and an impending Earth invasion this postman is about to go on the postal route from hell.
