The Sulaco was boarded shortly after Ripley, Hicks, Bishop and Newt go into hypersleep after the events in Aliens by Weyland Yutani personnel. Ripley and co. are taken prisoner and kept in suspended animation as Weyland Corp studies them. They extract DNA from each of them and clone them(which due to the methods employed, accelerate their natural aging process). These clones are placed back on the Sulaco with eggs so that Weyland can view/record the lifecycle of the Aliens. This explains the events in Alien 3 and Resurrection.
The film begins with Bishop slowly waking Ripley and Hicks along with Newt(who has been recast due to obvious real life aging issues). Bishop explains to Ripley and Hicks that he managed to free them from a top secret Weyland holding facility. He shows them security footage of Weyland extracting their DNA and growing clones of them and then replacing them in the Sulaco with Alien eggs on board.
Bishop manages to find out that LV 426 was indeed the Alien homeworld all along and that Weyland had purposely set up mining colonies there to study the Alien lifecycle before contact was lost with Hadley's Hope. He goes on to explain that they need to nuke the planet from orbit but Bishop has decoded a faint distress signal from somewhere below LV 426's surface.....that of Hudson's. Hicks gathers a team of marines that "can be trusted" and realizes that they must again go back to LV 426 to investigate Hudson's distress signal(and see if he's even alive before they nuke the planet for good).
Once on the planet, they re-enter the Derelict as that's where Hudson's distress signal seems to be coming from. They find new underground tunnels leading to a massive, secret underground Weyland Yutani facility(remember that concept art Blomkamp released?
) where Hudson managed to escape to and is now being held against his will.
Naturally, once they rescue Hudson, they realize they must get back into orbit to nuke the entire planet. More Aliens are let loose from maniacal Weyland scientists along with a Queen and King alien as our heroes must fight their way back up to the planet's surface and get back into orbit to end the nightmare for good.
While this story will probably be dismissed as a bad "fan fiction", the few Alien fans I work with really seem to dig the basic premise of the plot as it simply doesn't dismiss Alien 3 and Resurrection as "bad dreams". Those movies *did* in fact happen but with CLONES of our heroes.
Go easy on me.
