The war against the Bugs continues! A Federation Starship crash-lands on the distant Alien planet OM-1, stranding beloved leader Sky Marshal Anoke and several others, including comely but tough pilot Lola Beck. It's up to Colonel/General Johnny Rico, reluctant hero of the original Bug Invasion on Planet P, to lead a team of Troopers on a daring rescue mission.
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.
Maciste's village is attacked by pirates. The women, including Maciste's fiancee Guja, are carried off to Salmanak, where dwells the lair of the blood drinking Kobrak. Maciste vows to rescue them.
As the world nears it's end, a woman finds herself overwhelmed by emotion. She searches for closure as threats mount.
