it might go along the lines of this: the Government has found a new intergalactic planet and they try to send NASA, but they denied so they'll go to the planet by themselves....a group of 6 go, and when they reached the planet they found out that it is LV-426 that drifted off it's orbit and heading straight towards earth.....so when the 6 ppl discover the alien eggs, they take them on the ship to examin them, but one of the crew finds a 'dead' xenomorph,brings it onto the ship thinking that it's dead....which it is not dead and begans to kill all the crew............
wow! what a long story line
