The story starts out in Antarctica, where a group of scientists is bunkered until one day they are disturbed by the sounds of gunshots coming from a Norwegian helicopter, apparently trying to kill a runaway dog. They miss their quarry, and the Norwegians end up getting offed, with no explanation as to what their problem is. Fearing more violence, the American crew travels to the Norwegian camp, only to find some very odd occurrences, including a mangled humanoid body that has normal internal organs. Then, the dog reveals that it is not really a dog, but some sort of alien organism with the power to mimic other life-forms and dominate until it takes over everything around it. The men of the camp are its next intended victims, and soon, no one can trust the others. Kurt Russell, Keith David, and Wilford Brimley appear. Directed by John Carpenter.
The moon of Endor gets attacked by a vicious band of thuggish Sanyassan marauders, whose ancestors also crashlanded on Endor some time ago, and a powerful shape-shifting sorceress named Charal under the leadership of King Terak. They attack the Ewok village, taking the crashed Towani ship’s power source after killing Cindel’s family, then take away all of the Ewoks except Wicket back to their dungeons as prisoners.
While roving the forest, Cindel and Wicket encounter a mysterious creature named Teek who leads them to the home of a grumpy hermit named Noa Briqualon, who we come to find has also crashlanded there. Noa wards them off, but his icy exterior melts to friendship, leading to Teek and Noa helping them on their quest to free the imprisoned Ewoks from the marauders’ castle. King Terak is confident that the powerful crystal that is an energy cell used by the Towani family star cruiser has magical powers. The power, Terak feels, will get them off of Endor and that Cindel must be some sorceress who can tap into those powers.
