It's "The Military Academy of the Damned!"

Oh, my! "Threshold", CBS' new scifi fare on Friday nite, has just taken cheese to a place no cheese has gone before... Aliens have taken over the students at a military academy and are seeking to destroy all humans!!! The heroine has just set off the sprinkler system to wash the powdered cheese dusting this second episode.

I don't hold out much hope for this series. ABC's "Invasion" looks far creepier, and better written.
