Galaxy of Terror is a 1981 science fiction movie about a crew of survivors who crash on strange planet filled with grotesque creatures. When the space vessel Quest crash lands on the mysterious planet, Cabren (Edward Albert), Alluma (Erin Moran), Ranger (Robert England) and other members of the crew leave the ship to find other inhabitants. After wandering across the landscape, they stumble across another ship, which is the scene of a massacre. The crew splits into two teams to continue the search when they come across a massive pyramid-shaped structure. One by one, the crew members succumb to increasingly violent deaths at the hands of large creatures or machinery. Cabren and Ranger soon realize that one of their crew members is not who he or she seem to be and is keeping a dark secret about the pyramid. The duo must find out the true meaning of pyramid's power in order to save the rest of the crew.
