THRESHOLD Episode 2 "Blood Of Children"

A new infectee is discovered, but it isn't one of the crew off the ship. He was the janitor of a military academy. The Red Team immediately launch into action and discover that a plane passed the site of the alien appearance and picked up the signal. Later, at the academy, one of the students was trying to get his computer to work again and infected the janitor and one of the older students. That student has one intention, to put the signal onto the internet. That will infect a third of the population of the USA within a week.
