Alien abduction. Three young Marines are plucked from a battlefield of the Korean War by anonymous creatures. A Girl Scout troop is taken from a wilderness area while on a camping trip. They can't view or communicate with their captors, instructions coming only via pictures on a video screen. It looks as if they've been abducted to exterminate dangerous intelligent lifeforms, and will be supplied with advanced weapons. Among their rewards seem to be voluptuous companions for the Marines, handsome young men for the Girl Scouts. But it all turns out differently once they've been dropped into the middle of a trackless prairie. Where are they?—no idea. On what kind of world have they been landed?—nothing like in the pictures. Fancy ray guns?—no such thing. Lovely women and handsome men for companions?—don't count on it.
