A group of elite interstellar commandos crash lands on a planet while transporting an alien prisoner. Amidst shifting loyalties among the group, they must track down and recapture the escaped creature, alive.
The escaped prisoner sets up traps and picks the commandos off one by one. Soon there are only Commander Karza and Lieutenant Centauri 7 left. Centauri wants to kill the alien and be done with it, but the Commander insists that he be taken alive, regardless of the mounting cost. The two engage each other in a tense standoff, as Centauri demands to know why the prisoner is so important. The commander then reveals that the prisoner is the only survivor of its kind, whose planet was destroyed in war, and that he "plans to return the favor."
The standoff is interrupted when the commander is killed by a sniper...
