In the sequel to Paul Verhoeven's loved/reviled sci-fi film, a group of troopers taking refuge in an abandoned outpost after fighting alien bugs, failing to realize that more danger lays in wait. We are sent back to the battlefield, as the Federation's best Mobile Infantry unit are slowly being overpowered by the killer bugs. They are light years from the nearest reinforcements and are trapped on a remote outpost. They set up protection around the post, keeping all the bugs waiting for them to leave. But now the enemy is in the outpost, in a way which they would have never thought of.
