Well, Jazzcat, between us I think we saw the whole thing. We forgot it was coming on and picked it up about half-way through. What I got from the last half is that they think the aliens are trying to alter human DNA in some way. They had to destroy the ship to keep anyone else from finding it. While they were clearing the ship, the guy who had been affected by the "aliens" (Ethan from Lost--can't remember the character's name) attacked the woman and the military guy. She tried to shoot him, and it had no effect. Anyway, they all got off of the ship and it blew up. Later there was a discussion between the woman and the scientist (Brent Spiner's character) where he noted that there had been some alterations in the brains of 3 of the main characters--the woman, the military-type guy, and one of the others (didn't catch which). The woman had a very strange, vivid dream about being in a strange place surrounded by these huge crystals coming up from the ground, and got a call from the military guy that he had just had the same dream. The last scene we saw was when she got up and went to her refrigerator. When she closed the freezer door, the alien guy (Ethan from Lost) was standing there, and hadn't been there when she went into the kitchen. Very creepy...

I hope that made a little bit of sense. I missed the first half and I'm sick, so my memory of character names is non-existent at the moment. I also think I left some things out, but maybe someone else can fill in the details.
