An extermination unit from I.A.E.F (International anomaly execution force) is sent to Canterlot to eliminate what was presumed to be three high priority extraterrestrials, but soon finds there is much more than three. Will he manage to kill them? Or will he fall victim to failure? More importantly, how far will he have to chase them?

Ok, this may be one of the weirdest HiE fics I'll write in a long time, so get ready for one hell of a read.
NOTE: HiE means "Human in Equestria".
