"This was the day the universe trembled before the demon forces of the killer planet!"
Aura is the target planet of a special space mission. Two vessels and crews are sent there to survey. A successful landing opens a new alien landscape to explore, but the planet begins to affect the crews in unexpected ways. An older and failed expedition is uncovered revealing the horrible truth that the crew went mad and turned on each other. Evidence of a shadowy and eerie inhabitant race on Aura begins to sway the new crew's members. They must find a way to exit the planet before their minds are taken-over, and a similar bloody fate occurs to their own mission.
