Shadowfire (1985)

General Zoff is holding Ambassador Kryxix captive in his spaceship. Plans for a new type of spaceship are hidden in a micro-disc embedded in the Ambassador's spine. If Zoff had the plans, the empire would be in great danger, and it is only a matter of time until his inquisitors will discover them. The Emperor has assembled the so-called "enigma team", a group of six reckless mercenaries, to take care of the situation.
