The two best (not really) couriers of Space Post Express, cyborg Tod and human Phil, are ready for another dull day at the job. To their elation, they're given a special mission—one where they'll need to accompany Ariana, the stunning officer that saved them last time, and Phil's (supposed) soulmate!

Complications (predictably) arise when Phil, in his endless pursuit to impress Ariana, tries to "save" them from their "pursuers." Of course, that ends up with the unlikely trio stranded on an ex-prison planet taken over by its inmates—smugglers, slave traders, mobsters, and criminals of all kinds—and transformed into a pirate planet. Will they manage to complete their mission without blowing their covers, or will things blow up on their faces?
