A crew of escaped prisoners crash into a relay station over Jupiter carrying evidence of torture and murder. They must fight their way to the communication room to tell earth of these corporate crimes before the outpost burns.

I will give it a shot. It's more an ensemble piece, small band of plucky heroes battling against the odds kind of story.

Same thing here. Please focus on one main protagonist.
