From the inlay: Galactic Survey Vessel ORION is on a mission to map and explore the Hercules Cluster. After 20 years, the survey is almost complete apart from one small strange looking Nebula. The crew prepare to cross the intergalactic space by putting themselves into Sustained Low Energy Expenditure Process. However, during the intergalactic crossing, ORION is taken over by a force of strange alien mechanical beings - ZIMEN. When the crew re-energise, they find that many of the ship's systems have been terminated, all the computers reprogrammed in an alien language and ZIMEN everywhere. Can the crew overcome these obstacles and regain control of ORION. Time is against them as the ship's energy drains away. They must all work together using all their inbuilt capacities in order to free themselves from the dreaded ZIMEN.
