Federation trooper Johnny Rico is ordered to work with a group of new recruits on a satellite station on Mars, where giant bugs have decided to target their next attack.
The troopers of two starships have joined forces to terminate a massive bug attack at a Federation outpost. Before the mission can be completed and the survivors evacuated, one ship abruptly departs and goes inexplicably dark. The remaining battle-hardened troopers race to the rescue only to discover that the threat from the bugs is about to hit home.
Derrick, a racially-confused Irishman raised in the hood by a black family is having the worst day ever. Determined to prove to his fed-up mother and would-be girlfriend that he's not a screw-up, he sets out to do one thing right (get some milk) and even that proves to be a challenge! Hilarious encounters with racist red-neck cops, local gangsters and 'flamboyant' pawn shop owners ensue, and along the way Derek shows that he can actually do things for others and maybe even get his own life together.
