Strange events happen that lead Jack to suspect something bigger is going on with Julia as their son Eric claims he saw "silver men" cleaning the house in the middle of the night, and Jack finds a strange device found underneath Amanda's bed that wasn't there before, memory chips on their son's MP3 player have turned to dust, Julia has not only become distant but has also become abusive to her family, and Julia was seen driving one night with an unidentifiable passenger in her car. On that same night, Julia is injured in a car crash, and Jack is recruited to consult at Xymos, because the project manager, Ricky - a good friend of Jack's and former colleague - is having software issues with the nanobots.
