Mr. Frederick is a high school teacher. No fun, Low pay, High stress. He wishes for a better job and "kinda" gets what he asks for. When a meteor with a school for aliens crashes onto Earth, Mr. Frederick will have to teach this class, or he will be killed by the Aliens. Now Mr. Frederick will have to teach a class of aliens, avoid the MIB, FBI, etc. and he will have to fight off alien threats. Maybe being a high school teacher wasn't that bad.
