Predator

Sent to eliminate a gun-running camp in Central America, United States Major Dutch Schaeffer and his commandos get more than they bargained for when they cross paths with a mysterious assassin. As members of their unit begin to disappear, Dutch, Dillon, and Blain conclude that whatever is hunting them is not of this earth. Every attempt at a tactical defense is a defeated for Dutch and company and it is only in the last stretch of their race to safety that their suspicions are confirmed and they encounter the alien nimrod face to face.
