Annihilator

A newspaper reporter, Robert Armour, is in a romantic relationship with another reporter, Angela. Angela, along with her friend, Cindy (a photographer for the paper) take a flight to Hawaii. When Angela and Cindy return from the vacation, they act strangely, causing Robert to be concerned, and the women turn out to be androids who try to kill Robert. An alien force planning on taking over the world caused Flight 508 to disappear; they abducted the human passengers and replaced them with identical-looking androids. Robert now becomes the hunter and hunted, knowing he must hunt down the androids.
